SA516 Grade 70 NM400 plate equivalent refers to normalized steel products. For steel plates and thin plates with a thickness of less than 40mm, we usually supply rolled steel coils. Plates with a thickness greater than 40mm should be normalized and supplied. The density of NM400 plate equivalent SA516 70 grade steel plate is 0.284 cu/in3 (7861 kg/m3).

Low-alloy high-strength steel grades are designed to have quite good notch toughness for their intended structural use. The applicability of the notch toughness of specific grades of low-alloy high-strength steel is either based on existing use experience or combined with the results of the impact test of notched specimens. In order to meet the very strict requirements of certain applications, some NM400 plate equivalent, low-alloy high-strength steels produced have excellent notch toughness. For example, controlled hot rolling technology is usually used to produce low-alloy high-strength steel plates for the manufacture of welded line pipes. Such steel pipes need to meet the requirements of relevant standards for notch toughness.

For stainless steel plate cutting, the choice of cutting method is determined by the thickness of steel plate. If the thickness of NM400 plate equivalent stainless steel plate is more than 20 mm, flame cutting is adopted, while the thin plate is suitable for plasma cutting. In addition, if the cutting requirements are relatively high, laser cutting can be used. In addition, if the NM400 plate equivalent stainless steel plate is used as a billboard, plasma cutting is adopted, Because it uses thin plates.

The tensile strength of A36 steel plate is 58-80 Ksi (about 400-550MPa), and the yield strength is 36 Ksi (about 250MPa); the tensile strength of Q235 steel plate is 370-500 MPa, and the yield strength is 235MPa; the tensile strength of SS400 steel plate is 400-510MPa, and the yield strength is 245MPa. For the mechanical properties of NM400 plate equivalent, SS400 steel plate and Q235 steel plate, the thickness of steel plate is less than 16mm. It can be seen from the above data that ASME A36 and Chinese Q235 are named after the yield strength of the material, while SS400 is named after the tensile strength of the material.

When providing technical services on site, the after-sales personnel shall strictly abide by the safety rules and regulations of the construction site, consciously take safety protection measures (such as wearing safety helmet when entering the construction site), accept the supervision and management of the site; without permission on the construction site, they shall not dismantle, smear or damage any goods; the commissioning of contract goods shall be carried out under the supervision of the site supervisor If necessary, it shall be approved by the site supervisor or the person in charge of the project department.
