What are the quality features of S420ML material

SA387 Gr 11 Cl 1 steel has high brittle resistance, and also has good impact toughness in low temperature environments. It is suitable for refining and gas treatment in hydrogenation reaction and conversion equipment at high temperature. The maximum thickness of S420ML material products can reach 250mm. According to different thickness and impact requirements, the heat treatment of A387 Gr 11 Cl 1 plate can choose normalizing and tempering or normalizing and rapid cooling and tempering.

Focusing on the energy conservation and emission reduction objectives proposed by the municipal government, the company gives full play to the advantages of S420ML material circular economy formed after the comprehensive completion and operation, and vigorously promotes the implementation of energy conservation objectives. Through measures such as energy saving, technological innovation and S420ML material management strengthening, the energy saving target of annual reduction of added value energy consumption by 7%. It has made great contribution to energy saving of over completion.

Penetration testing technology is only suitable for detecting surface defects. It uses penetrant to apply on the surface of the S420ML material steel plate, then wipes the excess penetrant with the cleaning solution, and then smears the developer. The penetrant remaining in the defect is adsorbed by the developing material, so as to observe the shape of the defect and determine the type of defect. This S420ML material method requires multiple wipes before and after the inspection, the process is more cumbersome, and can not detect internal defects and rough and dirty steel plates.

Weathering steel plates have an excellent corrosive resisting property like resistance to crevice and pitting corrosion, resistance to corrosion and oxidation. This plate also has resistance to chloride corrosion cracking and stress corrosion. These plate are not affected very easily by acids and environmental rust and works in the sulfide atmosphere. S420ML material, Weather resistant steel plates have excellent workability, formability, easy to install, easy to fabricated, machinability, durability, reliability.
