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, good low-temperature impact toughness. 42crm

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, good low-temperature impact toughness. 42crmo steel plate is also heat-resistant steel, which has high creep strength and endurance strength at high temperature, and can work for a long time at 500℃.

The company specializes in the research and development, production and sales of ZQS700L cold forming automobile structure steel seamless pipes, longitudinally welded pipes, large-diameter welded pipes, API 5L welded pipes, spiral welded pipes, and large-diameter thick-walled straight seam steel pipes. The company has ZQS700L cold forming automobile structure steel five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,ZQS700L cold forming automobile structure steel rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.

Welding is mainly used for manufacturing metal structure parts, and also for manufacturing machine parts. The welding connection performance is good, and it is convenient to weld ZQS700L cold forming automobile structure steel steel plates, profiles or castings and forgings according to the needs. At the same time, welding can also connect different shapes and sizes (plate thickness, pipe diameter) or even different materials, so as to reduce weight, save materials, optimize resources and other purposes. The welding structure has high rigidity, good integrity, and easy to ensure air tightness and water tightness, so it is especially suitable for ZQS700L cold forming automobile structure steel manufacturing hollow structures with high strength and large rigidity (such as pressure vessels, pipes, boilers, etc.).

Chromium element (Cr element) can improve the strength and hardness of ZQS700L cold forming automobile structure steel, carbon steel in rolling state, reduce elongation and area reduction. When the chromium content is more than 15%, the strength and hardness will decrease, while the elongation and reduction of area will increase correspondingly. It is easy to obtain high surface processing quality for steel parts containing chromium after grinding. The main function of chromium element (Cr element) in quenched and tempered steel structure is to improve hardenability, so that the steel has better comprehensive mechanical properties after quenching and tempering.
