Our quality control department will do inspection for details of the steel materials A709 grade HPS70W bridge steel plate before delivery. We would invite the customer side to attend the inspection together. If they can not come, we will also take rich pictures for them to check. Meanwhile, we will publish inspection report and send them the PDF version. Besides, we accept any third party inspection such as SGS, BV, etc. And our quality control department will support the third party to inspect the steel materials smoothly and try our best to deliver the qualified steel materials to customers earlier.
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 ℃). A709 grade HPS70W bridge steel plate Smelting method: It is smelted by electric furnace + refining outside the furnace + vacuum degassing, and should be fine grain killed steel.
Low-alloy steel plates have low carbon content, and because ferrosilicon is not used for deoxidation, the silicon content in steel is often <0.07%. The outer layer of rimmed steel is crystallized in a rimmed state, so the surface layer is pure and dense, the surface quality is good, and the Zhengzhou low alloy steel plate A709 grade HPS70W bridge steel plate has good processing performance. Rimmed steel does not have large concentrated shrinkage cavities, uses less deoxidizer, and the cost of steel is low.
