ASME SA 53 seamless pipe is a low carbon A514 grade S alloy steel plate steel pipe with carbon content of 0.25% and manganese content of 0.95%. BBN exports all sizes of seamless, black welded and hot-dip galvanized A514 grade S alloy steel plate steel pipe of ASME SA 53. It is also known as soft steel pipe and is easy to produce.
40Cr steel plate is one of the most widely used steel in machinery manufacturing. After tempering, it has good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel A514 grade S alloy steel plate is good. It can be hardened to Ф28 ～ 60mm during water quenching and Ф15～40mm during oil quenching. When the hardness is HB174～229, the relative cutting workability is 60%. The steel is suitable for making medium-sized plastic molds.
Both steelmaking and ironmaking are carried out by oxidation-reduction reaction, but there are great differences between them in reaction objects: ironmaking is to reduce iron, while A514 grade S alloy steel plate steelmaking is to remove excessive carbon and other impurities in pig iron, so there are relations and differences between them in actual operation. There are three main methods of A514 grade S alloy steel plate steelmaking: converter, electric furnace and flat furnace. The converter steelmaking process is most widely used.
The company adheres to the business philosophy of "good quality, customer first, honesty and trustworthiness", and strives to provide customers with high-quality A514 grade S alloy steel plate products and excellent services. Our company's products A514 grade S alloy steel plate are widely used in petroleum, chemical, power station, boiler and other industries, mainly used in reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied gas tanks, nuclear energy reactor pressure shells and other equipment.
