Whether welding of SMA490BW corrosion-resistant plate can be quenched to obtain martensite

The company produces seamless steel pipes such as GB, ASTM, etc. all year round, including low and medium pressure boiler steel pipes, high pressure boiler steel pipes, welding of SMA490BW corrosion-resistant plate seamless steel pipes for ships and petroleum cracking welding of SMA490BW corrosion-resistant plate steel pipes, Seamless steel pipe, oil sleeve steel pipe, pipeline steel pipe, hollow sucker rod, common fluid steel pipe, structural pipe, kauden steel pipe, seawater corrosion-resistant titanium pipe and imported alloy steel pipe are used for high-pressure fertilizer equipment. The products are widely used in petroleum, chemical, electric, boiler, ship, machinery and other industries, and have been sold all over the country. Many welding of SMA490BW corrosion-resistant plate products have been exported to the Middle East, India, Southeast Asia and Europe and America.

ASTM A335 P11, P22, P91 pipes are commonly used in power plants and chemical-petrochemical industry, while P9 and P5 pipes are mainly used in petroleum refineries. BBN steel company supplies ASTM A335 Cr-Mo alloy steel seamless pipes sized from 1/2″ to 24″ranging in wall thickness from SCH20 to XXS or even thicker. The welding of SMA490BW corrosion-resistant plate specification covers nominal wall and minimum wall chrome-molybdenum( also known as Cr-Mo, or Cr-Moly) alloy steel pipe intended for high-temperature application.

The price of common carbon plate is relatively low compared with other kinds of steel welding of SMA490BW corrosion-resistant plate, and it can be used in a wide range of occasions, such as construction, machinery manufacturing, etc. Therefore, carbon plate is favored by users all over the world. And because of its large demand, fast circulation, the steel suppliers and exporters would like to keep huge carbon plate stocks, and thus the delivery is very quick. We also have large quantity stock for carbon plates. And we provide further processing for the carbon plate.

The main raw material of welding of SMA490BW corrosion-resistant plate, hot rolling coil is billet. After heating the billet, the strip made from the coarse and fine rolling mill is cooled to a certain temperature by specific cooling, and then the cooled steel strip is made into rolled steel strip by coiler. But generally, according to the buyer's demand, the manufacturer can further process the cooled steel strip into steel plate or flat coil and other products.

The requirements for toughness impact energy of welding of SMA490BW corrosion-resistant plate, S355JR steel and S355J2 steel are different, other mechanical properties and various requirements are the same.S355JR steel toughness impact energy requirements: 20 ℃, impact energy ≥ 27JS355J2 steel toughness impact energy requirements: - 20 ℃, impact energy ≥ 27JAs the temperature decreases, the impact energy of the same steel will gradually decrease, so S355J2 steel is more expensive than S355JR steel.

We have a professional production team and high-quality production equipment, and we also have a great welding of SMA490BW corrosion-resistant plate advantage in price, with its own factory, large-scale production to reduce the price. Strictly control each production line to ensure the welding of SMA490BW corrosion-resistant plate production of high-quality steel plates, steel pipes and other products that meet customer requirements.
