Low carbon alloy steel, the total amount of alloy elements is generally ≦3%; the low carbon alloy steel strength is significantly higher than that of carbon steel, with better plasticity and toughness, and weldability is acceptable; low alloy steel includes carbon manganese series, carbon manganese vanadium series, SA573 Gr.58 mild steel high strength chromium molybdenum series, chromium molybdenum vanadium series. Molybdenum and chromium molybdenum vanadium alloy steels are commonly used as materials for hydrogen corrosion resistance, high temperature sulfur or hydrogen sulfide corrosion resistance and heat resistance (sub high temperature).
Manganese is used to deoxidize and remove sulfur in steel when making steel. It is an beneficial element in SA573 Gr.58 mild steel high strength steel. Manganese has a strong ability to deoxidize and remove sulfur, it can eliminate or reduce the hot brittleness caused by oxygen and sulfur, and improve the strength and hardness of SA573 Gr.58 mild steel high strength steel.
We have a stable system and professional human resource management work as the support, from the six aspects of guidance, cohesion, incentive, constraint, radiation and stability, we continue to introduce, modify and train employees from concept to action, and shape employees through constant guidance of common values.
Both the cross rolling method and the extrusion method must first heat the tube blank or ingot, and the steel tube produced is called hot rolling tube. Steel pipes produced by hot working can sometimes be cold worked as required. There are two methods of cold working: one is cold drawing, that is, drawing the SA573 Gr.58 mild steel high strength steel pipe through the drawing die to make the steel pipe gradually thin and elongate; the other is cold rolling, which is the method of applying the hot rolling mill invented by the menesmann brothers to cold working. The cold working of SA573 Gr.58 mild steel high strength seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.
