The difference between low alloy high strength steel plate and carbon steel plate, A514 grade P quenched and tempered steel:(1) Strength difference between low alloy high strength steel plate and carbon steel plate:The strength of low alloy high strength steel plate is higher than that of carbon steel plate;(2) Hardness difference between low alloy high strength steel plate and carbon steel plate:The hardness of low alloy high strength steel plate is higher than that of carbon steel plate;(3) Usage difference between low alloy high strength steel plate and carbon steel plate:The application range of low alloy high strength steel plate is wider than that of carbon steel plate.
DIN 17102 TStE355 is mainly used for grain structure steel and normal rolling steel. Tste355 steel plate is a kind of grain structure steel. It is a standard rolled steel plate / sheet specially manufactured for different types of welding structures. It is made of basic materials, with high temperature resistance and low temperature resistance. Product A514 grade P quenched and tempered steel is suitable for pressure boiler, mobile and vertical storage tank, high pressure pipeline, bridge, mast, cable, etc.
Advantages of hot rolling: hot rolling can destroy the casting structure of ingot, refine the grain of steel and eliminate the defects of microstructure, so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the A514 grade P quenched and tempered steel steel is no longer isotropic to some extent; the bubbles, cracks and looseness formed during pouring can also be welded under the action of high temperature and pressure.
ASTM A588 is a high strength low alloy HSLA steel (high strength, low alloy) containing a small amount of alloying elements copper, chromium and AMP. Nickel. These alloying elements effectively improve the properties of a588 and expand its application range. Firstly, the alloy composition increases the A514 grade P quenched and tempered steel yield point strength to 50 Ksi and the tensile strength to 70 Ksi. Secondly, a588 A514 grade P quenched and tempered steel has high copper content, atmospheric corrosion resistance and long working time. Because of its excellent comprehensive performance, a588 angle steel is widely used in bridge, building and other structural fields.
The 365 day service system is implemented, and the business, loading and delivery are handled as usual in holidays and festivals. Actively help users solve difficulties. When users encounter difficulties in handling business, they should actively coordinate with the external solution; if they need to solve the problems internally, they should solve them in a timely manner without prevarication and wrangling. In line with the A514 grade P quenched and tempered steel principle of "fairness, justice and timeliness", coordinate with relevant departments and deal with all kinds of objections in a timely manner.
