Chemical composition of S355M strength grade

Our team is a dynamic, but also mature and steady team. The talents are made of different ages. There are experienced ones, and also creative ones, that also makes our company culture diversified. We have complete department structure, to make the whole work procedure run smoothly. For every step, we have special person to be in charge and responsible for our customer and update information to the customer in time. So you just need not worry too much to purchase steel materials from our company.

We have gradually formed four advantageous products of steel plate, steel pipe, S355M strength, stainless steel and special steel, and established our own processing center to meet the diversified needs of customers. At the same time, we also set up professional environmental protection, baby carriage and other projects. With the professional team and strong background of steel plate, steel pipe, stainless steel and special steel, it will drive the rapid development of other projects.

As per JIS G3101 standard, the Carbon (C), Silicon (Si) and Manganese (Mn) content of SS400 steel plate are not controlled. Phosphorus (P) content of S355M strength, JIS SS400 steel plate is 0.050% Max and Sulphur (S) content is 0.050% Max. The SS400 steel melting point is 1430 Degree Celsius, Brinell Hardness is 160HB, density is 7.85g/cm3, Young’s Modulus is 190-210Gpa. The strength and elongation of JIS SS400 steel plate varies with thickness. Generally, the tensile strength of SS400 steel plate is 400-510 Mpa. Elongation is above 21%. Yield strength ≥245Mpa for thickness≤16mm. When the JIS SS400 steel plate is thciker than 100mm, the yield strength shall not less than 205Mpa.

Steel can be divided into ordinary steel and special steel, which is an important symbol of a country's steel production level. The special steel includes spring steel, round steel, die steel, heat-resistant steel, wear-resistant steel, bearing steel and so on. Compared with ordinary steel, the S355M strength special steel has better physical properties, higher strength, stronger compressive strength and better accuracy. At the same time, the special steel has better chemical properties, such as high temperature resistance, low temperature resistance and corrosion resistance.

Compared with other fast-moving consumer goods, steel consumption is obviously different, with a wide range of use and a long service life. Therefore, the quality and service of steel materials are particularly important. Service is always one of our top concerns, especially after-sales service. We have mature after-sales service team, and can help you solve problems professionally during application of the steel materials.
