⛏️ Bucket Tooth Steel | Built for Impact & Abrasion

Excavator bucket teeth work in some of the harshest conditions in construction.

They are constantly exposed to impact, abrasion and heavy loads — so the steel needs to do more than simply provide high strength.

It needs the right combination of toughness, hardness and wear resistance to handle repeated impact while maintaining service life.

🔹 Grades We Supply

Depending on the working conditions and required performance, commonly used grades include:

• 30CrMnSiA — high strength, toughness and good wear resistance
• 30CrMn — suitable for applications with moderate impact and wear
• 30Cr2MnSiMo — Mo-alloyed grade designed for more demanding conditions, with improved hardenability and temper resistance

🔹 Typical Applications

🦾 Excavator bucket teeth
🦾 Bulldozer blades & wear parts
🦾 Mining and construction machinery components
🦾 Other heavy-duty, high-impact wear parts

Material selection depends heavily on the working conditions.

For equipment operating in highly abrasive soil, rock or mining environments, the required balance between impact toughness and wear resistance can be very different from standard construction applications.

📦 Our Bucket Tooth Steel Supply

We supply 30CrMnSiA, 30CrMn and 30Cr2MnSiMo in:

• Round bars
• Forgings
• Customized forged components

Available services include:

• UT testing
• Cutting to required lengths
• MTC / Mill Test Certificate
• Customized forging & machining through our downstream processing partners

🔩 ASTM A105 | A Forged Choice for Fl**ges & Valve Components

For valves, fl**ges and pressure-containing piping components, material reliability matters.

ASTM A105 is a carbon steel forging specification widely used for forged fl**ges, valve components and pipe fittings, particularly in pressure piping applications.

Why is A105 so commonly used?

🔹 Forged structure
The forging process provides a dense, uniform structure suitable for pressure-containing components.

🔹 Good mechanical properties
A105 offers a practical balance of strength and toughness for a wide range of piping applications.

🔹 Versatile processing
It can be supplied as forged material and further processed into fl**ges, fittings and valve components according to project requirements.

🔹 Widely specified
A105 is a familiar material specification across the oil & gas, petrochemical, power and general piping industries.

Typical applications:

⚙️ Pipe fl**ges
⚙️ Valve bodies & covers
⚙️ Pipe fittings & couplings
⚙️ Pressure piping components
⚙️ Oil & gas and petrochemical equipment

Commonly referenced grades include:
🇺🇸 ASTM A105
🇨🇳 20 / 20Mn — similar carbon-steel grades used in related applications
🇪🇺 C22.8
🇯🇵 S20C

Equivalent grades should always be confirmed against the applicable standard, chemical composition and mechanical requirements.

📦 Our A105 Supply

We supply ASTM A105 forged bars and forgings, with:

• UT testing
• Cutting service
• MTC / Mill Test Certificate
• Customized machining through our downstream processing partners

For valve and piping projects, we can also supply WCB, F11, F22, CF8, CF8M and other related materials.

⚙️ Gear Steel | Built for Repeated Load and Wear

Gears may look simple, but they work under some of the most demanding conditions in a machine.

Every rotation brings repeated contact stress, impact and friction. That’s why gear materials need more than just high strength — they also need a good combination of toughness, fatigue resistance and wear resistance.

That’s where gear steels come in.

🔹 Common Gear Steel Grades

Depending on the application and required heat treatment, commonly used grades include:

🇨🇳 20Cr · 20CrMnTi · 20CrNiMo · 42CrMo
🇯🇵 SNCM series
🇺🇸 AISI 8620 · AISI 4140
🇪🇺 20MnCr5 · 18CrNiMo7-6

🔹 Heat Treatment Matters

Gear steels are often combined with heat treatment processes such as:

• Carburizing
• Quenching & tempering
• Nitriding

These processes can help achieve a hard, wear-resistant surface while maintaining a tougher core, depending on the steel grade and application.

🔹 Where Are They Used?

⚙️ Automotive transmission gears
⚙️ Construction machinery
⚙️ Wind power gear systems
⚙️ Shipbuilding and heavy-duty equipment

📦 Our Gear Steel Supply

We supply 20Cr, 20CrMnTi, 20CrNiMo, 42CrMo and other gear/alloy steels in:

• Round bars
• Plates
• Forgings

We can also provide UT testing, cutting, MTC and customized machining services through our downstream processing partners.

🔩 Cr-Mo Steel | For Applications Where Strength Matters

When standard carbon steel isn’t enough for the job, Chromium-Molybdenum (Cr-Mo) steel is often the next material to consider.

The combination of Chromium (Cr) and Molybdenum (Mo) improves the steel’s strength, hardenability, toughness and wear resistance, making it suitable for demanding mechanical applications.

Why choose Cr-Mo steel?

✔️ Higher strength and hardness
✔️ Better toughness and fatigue resistance
✔️ Good wear resistance
✔️ Suitable for heat treatment
✔️ Reliable performance in demanding working conditions

Common grades we supply:

• 30CrMo
• 35CrMo
• 40CrMo
• 42CrMo

Depending on the grade and application, these materials are commonly used for:

⚙️ Heavy-duty shafts & connecting rods
⚙️ High-strength bolts & fasteners
⚙️ Automotive and construction machinery components
⚙️ Molds and other high-strength mechanical parts

You may also see Cr-Mo grades specified under different standards, such as SCM440, SAE 4140 and 42CrMo4, depending on the market and application.

📦 Our Cr-Mo Steel Supply

We supply Cr-Mo round bars in hot-rolled and forged conditions, with:

• UT testing
• Cutting to required lengths
• MTC / Mill Test Certificate
• Customized machining through our downstream processing partners

🔩 Looking for a stronger alternative to plain carbon steel?

40Cr round bar is a material we frequently supply for mechanical and engineering applications where higher strength, hardness and hardenability are required.

With chromium as its main alloying element, 40Cr offers better overall performance than conventional carbon steels such as 45 #, especially when heat treatment is involved.

Where is 40Cr commonly used?

⚙️ Shafts & axles
⚙️ Gears, couplings & pins
⚙️ High-strength bolts and fasteners
⚙️ Automotive components
⚙️ Mold bases and other machinery parts

Common equivalents:
🇨🇳 40Cr — GB/T 3077
🇯🇵 SCr440 — JIS
🇺🇸 SAE 5140
🇪🇺 41Cr4 — EN

📦 Our 40Cr Supply

We offer hot-rolled and forged 40Cr round bars in various sizes and specifications.

Available services include:
• UT testing
• Cutting to length
• MTC / Mill Test Certificate
• Customized machining through our downstream processing partners

Need further processing? We can also help coordinate machining and customized services according to your drawings or requirements.

Besides 40Cr, we supply 20 #, 45 #, 42CrMo and other carbon & alloy steel grades.

🔩 Why Is 45 # Steel So Common in Machinery?

When it comes to general mechanical components, 45 # steel is a grade that comes up again and again.

So, what makes it such a common choice?

The answer is its balance of strength, hardness, machinability and cost.

Compared with lower-carbon steel, 45 # can achieve higher strength and hardness, especially after heat treatment. At the same time, it remains practical for machining and manufacturing a wide range of mechanical parts.

That makes it a popular choice for components such as:

⚙️ Shafts & axles
⚙️ Gears & couplings
⚙️ Pins & mechanical parts
⚙️ Mold bases
⚙️ General engineering components

Commonly compared grades include:
🇨🇳 45 # | 🇯🇵 S45C | 🇺🇸 AISI 1045 | 🇪🇺 C45

At the end of the day, choosing steel isn’t always about finding the “strongest” grade. It’s about finding the right balance between performance, processing requirements and cost.

📦 Need 45 # round bar?

We can supply hot-rolled and forged 45 # round bars, with services including UT testing, cutting and MTC.

We also supply other carbon and alloy steel grades according to your requirements.
