42CrMo steel is an ultra-high-strength steel with high strength and toughness, good hardenability, no obvious temper brittleness, small deformation during quenching, and high fatigue limit and multiple impact resistance after quenching and tempering. It has good low-temperature impact toughness and high creep strength and durable strength at high temperatures.
9SiCr steel has good forging properties. Because it is easy to decarburize, 9SiCr steel needs to be heated in a neutral atmosphere or protective atmosphere furnace. By applying forging heat quenching and tempering treatment, a fine tempered sorbite structure can be obtained, which simplifies the process, saves time and energy, and has both good cutting performance and ideal waste heat treatment structure.The corresponding trademark of 9SiCr steel in other countries is DIN 1.2067、DIN 100Cr6、L3 steel.
Q235 ordinary carbon structural steel is also called A3 plate.Q in Q235 represents the yield limit of this material, and the following 235 refers to the yield value of this material, which is around 235MPa. And as the thickness of the material increases, its yield value decreases. Because the carbon content is moderate, the comprehensive performance is good, the strength, plasticity and welding properties are well matched, and it is the most widely used. Mainly used in construction and engineering structures. It is used to make steel bars or construct factory building frames, high-voltage transmission towers, bridges, vehicles, boilers, containers, ships, etc. It is also widely used as mechanical parts that do not have high performance requirements.Our company can provide Q235 wire rod or round steel, square steel, flat steel, angle steel, etc.
