SAE4140 is a chromium-molybdenum alloy steel known for its high hardness, high toughness and good hardenability. This steel is widely used in the manufacture of parts that require high strength and toughness, such as automotive parts, construction equipment, oil and gas industry components, and machinery. Its mechanical properties include high strength, yield strength and good elongation. In addition, SAE4140 can be improved through heat treatment, such as quenching and tempering.
SCM420H is an alloy steel with high hardenability, no temper brittleness, good weldability, little tendency to form cold cracks, and good machinability and cold strain plasticity. It is usually used to manufacture mechanical parts that require high strength and wear resistance, such as bearings, gears, connecting rods, crankshafts, etc., and is widely used in the automotive industry, engineering machinery, and aerospace.
As a high-performance alloy structural steel, 16MnCrS5 steel has been widely used in many fields. Its excellent mechanical properties, good process performance and corrosion resistance make it an important material choice in industries such as heavy machinery, shipbuilding, automotive industry and petrochemical industry. With the continuous development of science and technology, the application prospects of 16MnCrS5 steel will be broader.
Mold Steel 5CrMnMo is developed on the basis of medium carbon steel by adding three elements of Cr, Mn, Mo. The steel is a hot work die steel with slightly poor hardenability and thermal fatigue resistance. Steel is suitable for various types of forging dies with high strength and high wear resistance.When higher toughness is required, electro slag remelting steel can be used.
SCM415 Steel is a high quality Quenched and Tempered Alloy Structural steel, It belong to the high quality medium carbon. SCM415 whose surface are processed through carburizing hardening treatment are used for the parts which need high toughness or wear resistance, such as cylinder piston, crankshaft, gears, pin, shafts and so on.
SAE4340 is a high-strength, low-alloy steel known for its outstanding toughness, strength and fatigue resistance, and is particularly suitable for applications such as aerospace, oil and gas, and the automotive industry. This material has excellent mechanical properties and wear resistance, and is often used to manufacture high-strength, high-wear-resistant parts, such as crankshafts for aircraft engines and gears for automotive transmissions. The development trend of SAE4340 steel focuses on improving material properties and production process improvements, while paying attention to environmental protection and sustainable development. This alloy steel plays an important role in the fields of aviation, automobiles, and energy due to its excellent performance and wide application prospects.
SAE1020 steel is a high-quality carbon structural steel that is usually used directly in the supplied state without heat treatment. Its advantages include high cost-effectiveness, good machinability, good welding performance and good formability. SAE1020 steel is widely used in mechanical parts, automotive parts, structural applications, fasteners, hand tools and equipment, agricultural equipment, pipes and tubes, and bicycle frames.
Steel C45R is suitable for mean loaded parts in vehicle, engine and machine engineering with enhanced workability at constant mechanical qualities (e.g. transmission shafts, gear wheels, clutch parts, bolts). Lowest application temperature -25°C. As a bright steel product it is used in the form of bars, bright, straight, in various conditions.
