Steel mill inventory of nm400 steel tensile strength increased

Every customer who has visit us and witness the steel materials before delievry will be impressed by our quality control departemnt. Even not come to inspect the steel materials before delievry, our quality control departemnt will also send inspection report to the customer. For each order, no matter its quantity and value, our quality control departemnt will make strict inspection before delivery, the inspection contents include apperance, tolerance, dimension, mark, special requirements of customers, etc. To guarantee our steel materials sent to the customer is qualified.

Steel plate is divided into rolling, hot rolling and cold rolling. The width of the thin plate is 500 ~ 1500 mm; the width of the thick plate is 600 ~ 3000 mm. Thin plates are classified according to steel types, including ordinary steel, steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, NM400 steel tensile strength, bearing steel, etc .; according to use, there are ship plates, pressure vessel plates, atmospheric corrosion-resistant steel plates, bulletproof steel plate.

Pressure vessel plates NM400 steel tensile strength are used to manufacture pressure vessel equipment in petrochemical, gas separation and gas storage and transportation equipment. It is required to have sufficient strength and toughness, good welding performance and hot and cold processing performance. The general heat treatment of Q345R plate is hot rolling, controlled rolling, normalizing. The impact temperature is normal temperature, 0 ° C, -20.

There is an inherent difference between the cold forming properties of low-alloy high-strength steel and carbon structural steel. First of all, a certain amount of permanent deformation of low-alloy high-strength steel requires greater force than NM400 steel tensile strength, carbon structural steel of the same size. Second, when low-alloy high-strength steel is formed, a slightly larger allowable amount for springback should be given. According to experience, unless the low-alloy high-strength steel is processed to control the shape of inclusions, it is necessary to use a larger bending radius than carbon structural steel during cold forming.
