s237jr a36 grade SMA400AW vessel plate hr ms ship building

The company adheres to the service concept of "you give the order to me and I leave the satisfaction to you". Over the years, our SMA400AW vessel plate steel products are supplied in time, with reliable quality and perfect and thoughtful after-sales service. Meanwhile, we have huge SMA400AW vessel plate steel stocks all the year round. The company long-term pursues the principle of quality first, customer first, quality for survival, reputation for development, and perfect service to win the users.

As people have higher and higher requirements for the quality of various steel processing products, the market demand for SMA400AW vessel plate, pickling steel coils is getting better and better. At present, they are mainly concentrated in the automotive industry, compressor industry, machinery manufacturing industry, spare parts processing industry, fan Industry, motorcycle industry, steel furniture, hardware accessories, electric cabinet shelves and various shapes of stamping parts. With the advancement of technology, hot-rolled pickled steel plates are currently involved in home appliances, containers, electrical control cabinets and other industries.

Steel plates for high-rise buildings have the properties of easy welding, earthquake resistance, and low-temperature impact resistance, and are mainly used in large-scale projects such as high-rise buildings, super-tall buildings, large-span stadiums, airports, exhibition centers, and steel structure workshops. Compared with ordinary Q235B / Q345B steel plates, these plates SMA400AW vessel plate for high-rise buildings have upper limits on yield strength and improved tensile strength, and have requirements for carbon equivalent and yield ratio indexes.

The advantage of hot-rolled stainless steel plate is that it can eliminate the damage caused by SMA400AW vessel plate metal structure in the process of ingot casting to a certain extent, eliminate some tiny defects in the structure, refine the grains of stainless steel material, promote the structure of steel closer, and improve the performance of the material as a whole. This kind of lifting is mainly manifested in the rolling direction, which can make the SMA400AW vessel plate steel no longer isotropic to some extent, and some defects such as bubbles, cracks and looseness formed during pouring can be eliminated under high temperature or high pressure.

As to the Chemical composition, the different content is a main on carbon content, while the carbon content of SMA400AW vessel plate, A283Gr. D is no more than 0.27% and it is higher than Grade C (≤0.24%) ; as to the mechanical property, the differences are tensile strength and yield strength, while the tensile strength of ASTM A283 Gr.D is 415-550MPa (60-80 ksi) and yield strength of ASTM A283 Grade D is 230MPa (33 ksi).

Due to other non-steel quality reasons caused by the customer dissatisfaction, to timely explain to the customer, and help them solve the problem, for the customer really because of their own reasons, to give patient reply.The process of objection handling is the process of our technical service.
