ASME SA203 is a low-nickel alloy steel, including five grades of A, B, D, E, and F. SA203 Gr.E steel plate impact temperature -101 ° C. SA203 Gr.D / E / F has good impact toughness and mechanical properties under low temperature working conditions, and is usually used in low temperature environments of -70 ～ -101 ℃ (the tempered state can be -107 ℃). Steel din 1.0037 Smelting method: It is smelted by electric furnace + refining outside the furnace + vacuum degassing, and should be fine grain killed steel.
A small amount of Nb is sufficient to obtain excellent comprehensive properties of Steel din 1.0037 etc. steel material, because at low Nb concentration, the yield strength of steel material increases faster and is proportional to the concentration, but when the Nb content is greater than 0.03%, the strengthening effect begins to decrease. Studies have shown that when the Nb content is greater than 0.06%, excess Nb will no longer strengthen the steel material.
Steel din 1.0037, Composite wear-resistant steel plate can be formed by laser processing, but in this process, there are still many factors that will affect the laser forming effect of composite wear-resistant plate, including the input laser energy, the geometric size of bending parts and the properties of materials. There is a close relationship between them. The influence of thermal physical properties and mechanical properties of composite wear-resistant steel plate on laser bending is complex.
The company focuses on two markets at home and abroad, and has a group of 56 experienced sales elites and professional and technical personnel. It can provide customers with drawing design, Steel din 1.0037 deep processing services and installation solutions. 20 years of project experience has provided high-quality carbon steel, alloy steel products and high-quality after-sales service to customers in many countries around the world. The company has won widespread praise from customers.
