The company adheres to the business philosophy of "excellent quality and integrity", aims to create a first-class enterprise in the S315MC hot-rolled pickled strip industry, takes circular economy and resource reuse as the main line, takes energy conservation, emission reduction and sustainable development as the purpose, relies on advanced equipment, perfect transportation infrastructure and good reputation, and strives to become a leading enterprise in the S315MC hot-rolled pickled strip industry with scientific management, high quality, first-class service and harmonious development

30CrMnSiA steel is a grade of alloy structural steel. The steel has high strength and poor welding performance. It is a high-strength quenched and tempered structural steel with high strength and sufficient toughness after quenching and tempering, and good hardenability. It has good workability, small processing deformation and good fatigue resistance. 30CrMnSiA steel is mostly used to manufacture various important parts with high load and high speed.

Compared with S315MC hot-rolled pickled strip, pressure vessel and boiler steel plates have such advantages: The pressure vessel and boiler steel should be pure, and the fracture structure of the boiler steel plate should be uniform without cracks and inclusions. Besides, the strain aging sensitivity is small, and the strain aging impact value of the pressure vessel and boiler steel plate is required to be no less than 50% of the non-aging impact value. That is why pressure vessel and boiler steel plate is first choice for fabricating pressure vessels and boilers, while S315MC hot-rolled pickled strip is not.

The effect of nitrogen on steel performance is similar to that of carbon and phosphorus. With the increase of S315MC hot-rolled pickled strip nitrogen content, the strength of steel can be improved, plasticity especially toughness can be significantly reduced, weldability becomes worse, and cold brittleness is intensified. Nitrogen with aluminum, niobium, vanadium and other elements can reduce its adverse effects, improve the performance of S315MC hot-rolled pickled strip steel, can be used as an alloying element of low alloy steel.

20 # material is a high-quality low-carbon carbon steel, cold-extruded, carburized and hardened steel. S315MC hot-rolled pickled strip, 20 # material has low strength, good toughness, plasticity and good weldability. Chemical composition of 20 # round steel bar: C: 0.17 ~ 0.23, Si: 0.17 ~ 0.37, Mn: 0.35 ~ 0.65, S: ≤0.035, P: ≤0.035, Cr: ≤0.25, Ni: ≤0.30, Cu: ≤0.25. 20# carbon steel mechanical properties: Shear strength 275 ~ 392MPa, Tensile strength is 253 ~ 500MPa, elongation min. 25%.
