1.7225/SAE4140/SCM440/42CrMo4 Alloy Steel Bar for mechanical
Introduction
42CrMo steel is an ultra-high strength steel with high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and multiple impact resistance after quenching and tempering, and good low temperature impact toughness.
Steel Grade
Chemical composition%
Heating treatment
Available Sizes
1) Weldability suffers with increasing chromium content;
2) High temperature strength and high pressure hydrogenation properties are promoted by chromium and molybdenum;
3) Molybdenum significantly reduces temper brittleness;
4) Chromium renders steel oil hardenable and increase hardenability;
5) Chromium molybdenum high tensile steel with yield strength of 550N/mm2
Applications
1) Suitable for manufacturing requirment a certain strength and toughness of large and medium-sized plastic mold, such as locomotive traction with the big gear, the supercharger drive gear, pressure vessle, rear axle, gear load connecting rod and a spring clip
2) Used to under 2000m deep well of oil drill pipe joint and the fishing tool
3)Used for bending machine mould

Company Profile
Guangzhou ChangFeng Steel Co., Ltd is located in Guangzhou city, it was established in 2012, and is an Professional import and export company with ten years experience of selling special steel, which mainly sells plastic die steel, hot work die steel, cold work mould steel, alloy structural steel, bearing steel, tool steel, stainless steel, carbon steel, etc.
We also act on behalf of exporting steels of mainly steel factories in China, including Baogang group, Shagang group, Wenfeng group, Xingcheng group, Dongte group, Daye and so on. We are full of export experience to the market all over the word, such as America, Germany, France, Italy, Turkey, Singapore, Thailand, Malaysia, Vietnam, Taiwan, and Middle-East.
At the same time, We offer the seamless steel pipe, welded carbon steel pipe, GI pipe, and special pipe. Fittings elbow, tee, reducer, cap, lap joint, flanges etc...This is better for our customer to buy the different products from China, while they are saving their time, but they can enjoy in our best serves.
