Procurement Of Outstanding 4130 Materials And Similar Steel Comparison - China

In industrial manufacturing, 4130 materials (corresponding to the Chinese grade 30CrMo) is a commonly used medium-carbon chromium-molybdenum alloy steel with high strength, good toughness and weldability.

The following is a comparative analysis of 4130 materials and similar steels (such as 4340, 4140, 304 stainless steel, etc.

).

Core performance differences

1 - Balance of strength and toughness:

4130 materials: Suitable for medium load scenarios (such as aviation structural parts) with good weldability.

4340 materials: Nickel-containing to improve low-temperature toughness, suitable for heavy-load impact environments (such as helicopter landing gear).

2 - Corrosion resistance:

304 stainless steel: Corrosion resistance is much better than alloy steel, but low strength and high cost.

3 - Processability:

4140 materials: High carbon makes cutting difficulty slightly higher than 4130, and preheating welding is required.

4130 materials: Easy to process in annealed state, suitable for complex parts molding.

4130 materials achieve a good balance between strength, toughness and cost, and is a highly versatile mid-range alloy steel; 4140 is suitable for higher strength requirements, 4340 focuses on toughness under extreme working conditions, and 304 stainless steel specializes in corrosion resistance scenarios.

When selecting, it is necessary to weigh the mechanical properties, environmental tolerance, processing costs and supply chain stability.

All in all, no matter in terms of product performance, quality, technology and service, our Songshun is professional and high-quality.
