Now the company's business A514 grade S alloy steel plate department, marketing department and information department constitute the market development network; the finance department, personnel department, logistics department, shipping department, document department and A514 grade S alloy steel plate after-sales service department constitute the service customer network.
ASME SA 53 seamless pipe is manufactured according to A514 grade S alloy steel plate ASME code. Because it belongs to low carbon steel, the surface hardness can only be improved by carburizing. If you are interested in BBN A514 grade S alloy steel plate ASTM A53 or ASME SA 53 carbon seamless pipe, please contact us for the latest price.
If a destructive accident occurs during the use of the boiler, it will cause serious losses. Therefore, other than some common strengths with A514 grade S alloy steel plate, the boiler steel plate must have good physical properties, mechanical properties and workability, and be strictly specified in the technical terms of the material standard to meet its safety in use. High temperature (above creep temperature) boiler steel plates are generally low-alloy heat-resistant steels, such as chromium molybdenum steel, chromium molybdenum vanadium steel, chromium molybdenum tungsten steel, etc.
Composition characteristics of Q420 alloy steel plate: 1.Low carbon: Due to the high requirements for toughness, weldability and cold forming performance, its carbon content does not exceed 0.20%. 2. Add manganese-based alloy elements. 3. Add auxiliary elements such as niobium, titanium or vanadium, which is beneficial to obtain fine ferrite grains and improve the strength and toughness of the Q420 alloy steel, A514 grade S alloy steel plate.
According to GB 11251 technical standard, the chemical composition of 40Cr structural steel plate is as follow: Carbon content is 0.37-0.44 %, Silicon content is 0.17-0.37%, Manganese content is 0.50-0.80%, Chrome content is 0.80-1.10%. 40Cr steel is usually in shape of 40Cr steel plates and bars. A514 grade S alloy steel plate, GB 11251 is for 40Cr structural steel plate with thickness range of 4-30mm. The tensile strength of 40Cr structural steel plate is 550-800Mpa. And its min. Elongation is 16%.
