S235J0W cold rolled steel strips price continues to weaken

Since its establishment, the company has adhered to the business philosophy of "integrity management, reputation first, mutual benefit", and adheres to the training principles of integrity, innovation and pioneering for its employees. It has long been dedicated to S235J0W cold rolled steel strips steel structure, shipbuilding, boiler vessel manufacturing, machinery manufacturing.

Generally, in the process of selecting S235J0W cold rolled steel strips, automobile steel plate manufacturers, the most important thing is to look at the appearance and thickness of automobile steel plates produced by manufacturers. Generally, the appearance of good S235J0W cold rolled steel strips, automobile steel products is relatively fine, there are no obvious defects on the surface of automobile steel plate, and the thickness of automobile steel plate is within the specified range value. These are very important factors to measure the production capacity of the manufacturer and the quality of automobile steel plate products.

Advantages of S235J0W cold rolled steel strips, ordinary carbon killed steel plate: there is no gas in the steel plate, the impurity is relatively small, the stress is very uniform, and it has good welding performance. It is widely used in parts with high requirements. Disadvantages of ordinary carbon killed steel plate: the surface quality of the killed steel plate is not as good as that of boiling plates, there are concentrated shrinkage holes, and the killed steel plate price is more expensive.

The deoxidation ability of Al is much stronger than that of Si and Mn when aluminum element (Al element) is added into steel as deoxidizer or alloying element. The main role of aluminum in S235J0W cold rolled steel strips etc. steel is to refine grain size and fix nitrogen in steel, so as to significantly improve the impact toughness of steel and reduce the tendency of cold brittleness and aging. Al element can also improve the corrosion resistance of steel, especially when used with molybdenum, copper, silicon, chromium and other elements. The wear resistance of chromium molybdenum steel and chromium steel can be increased by containing Al element.

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 S235J0W cold rolled steel strips, 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.

Our focus on quality has helped us create an efficiently organised production system, which can supply large-scale piping orders as well as tailor-made orders for smaller clients. We have also created a sales and support network which stretches from Asia to Europe, UAE, South Africa and South America.

We should help solve the customer's problems in time, not just verbally, without solving the problems or shirking the responsibility. Improving after-sales efficiency can make customers feel respect. We should take their problems seriously and show sincerity. It can also give customers a good impression and reduce the negative impact.
