EN steel grade S355J2 material material meaning

Our company is a large EN steel grade S355J2 material steel enterprise integrating steel plate production, sales and processing. It is a first-class agent of Shanxi Taigang, Shanghai Baosteel, Jiugang, Xi'an Huaxin, Taishan steel, Dongfang special EN steel grade S355J2 material steel and southwest special steel. It is a special dealer of famous steel plants in China, such as Columbus, NAS, acerinox, Outokumpu, Arcelor, nipponmetalindustry, nipponyakinkogyo, NSC, etc.

AISI4140 steel plate is used to make forgings that require higher strength and larger quenched and tempered section than 35CrMo steel, such as large gears for locomotive traction, turbocharger transmission gears, pressure vessel gears, rear axles, connecting rods with extremely high loads, and Spring clip. It can also be used for oil deep well drill pipe joints and fishing tools below 2000m, and can be used for molds of bending machines.

The corten plates EN steel grade S355J2 material offer high tensile, yield and mechanical strength at the elevated temperature. These plates provide high toughness and harness at the high temperature and cryogenic temperature as well. The application of corrosion Resistant Steel Plates is- these plates are used in the number of industries like landscape building, an automobile company, fertilizers, marine industry. The plate is used in because of its good elasticity, ductility, thermal and electrical conductivity. We follow all the industry-standard both national and international standards.

Penetration testing technology is only suitable for detecting surface defects. It uses penetrant to apply on the surface of the EN steel grade S355J2 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 EN steel grade S355J2 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.

The S355 steel material itself is divided into many grades, so it cannot be said that S355 is equivalent to which grade of the national standard Q345, EN steel grade S355J2 material. In engineering, usually S355JR steel is equivalent to Q345B steel, S355J0 steel is equivalent to Q345C steel, S355J2 steel is equivalent to Q345D steel, S355N steel is equivalent to Q345D steel, and S355NL steel is equivalent to Q345E steel.

From the order to the delivery, there are three quality inspections to ensure that the qualified rate of finished products is more than 100%. We promise that every order will be tracked in a timely manner to ensure that customers can receive goods safely and constantly listen to their opinions and suggestions, reflect on our own problems, and let customers feel at ease. We have a large warehouse in Shanghai and Tianjin, which can provide customers with sufficient sources of supply.
