Our company's a573 grade 58 high strength steel plate power boilers, heating furnaces of double bars, double high lines and medium and thick plates all adopt heat storage technology, which can fully use blast furnace gas; the ladle baking, Maerz active lime kiln and medium and thick plate heat treatment furnace all burn converter gas, which can improve the a573 grade 58 high strength steel plate utilization rate of secondary energy and realize negative energy steelmaking in steelmaking process.
For a573 grade 58 high strength steel plate, stainless steel buyers, the most troublesome issue is the fluctuating stainless steel price trend. For manufacturers who purchase in large quantities, even if the price of stainless steel fluctuates in a little, the price cost incurred after the batch is very large. So, what factors affect the trend of stainless steel prices? By analyzing these price trends, it is obvious that we can grasp the market price of stainless steel.
16MnDR steel plate is suitable for low temperature pressure vessels manufacturing. Grade 16Mn- indicates that the content of manganese (Mn) in the steel plate is relatively high, about 1% -1.6%, D- indicates low temperature, R- indicates pressure vessel. (Normally, when the content of a certain chemical element in steel is high, it needs to be marked in the material, for example, 1.6% manganese is written as 16Mn; certain elements such as Cr and Mo are higher, written as Cr1, Mo1, Such as 12Cr2Mo1R.) The normal delivery status is normalized delivery (Normalized).
After a certain period of time, the steel products will reduce the toughness and increase the hardness, which is called aging effect. Generally, this effect is strongest at 200-300 ℃. The aging tendency of a573 grade 58 high strength steel plate, low carbon steel (about 0.1% carbon content) is especially large, while high carbon steel and alloy steel containing molybdenum, barium or tungsten are not easy to produce aging. For boiler steel plate, it is required that the reduction rate of impact initial property is not more than 50%, or the absolute value of impact initial property is not less than 3-3.5KGM / cm2.
ASTM A285 grade A standard specification for pressure vessel plates. a573 grade 58 high strength steel plate, carbon steel, low- and intermediate-tensile strength. ASTM A285 grade A plates are normally supplied in the as-rolled condition. The plates may be ordered normalized or stress relieved, or both.Supplementary Technology: HIC Test I NACE MR0175 1 215 | Z25 | 235 | S57 | S57.1| S58 | S58.1 1S3 |S4 Thickness: 6MM to 300MM.Width: 1500mm to 4050mm.
