Zhengzhou BBN steel company was established in 2000. After more than ten years of development, it has formed a professional operation pattern integrating R&D, production, sales and after-sales service. In recent years, astm a573 grade 70 properties based on a high starting point and high technology, the company has vigorously developed various steel products astm a573 grade 70 properties and deep-processed parts, steel structures, precision castings, seamless pipes.
ASTM A514 steel is mainly used in places where high tensile strength and high yield are required, such as engineering vehicle lifting gears, large excavators, offshore platforms, etc. Different grades of A514 steel plate have different thickness, chemical composition and properties. However, the astm a573 grade 70 properties mechanical properties specified in ASTM A514 are similar to those of Q690 in China. A514 grade Q is generally used as the rack for offshore platform. Its hardness is between 230-390MPa, yield is greater than 630MPa, and tensile strength is more than 700MPa.
The mechanical properties of 20MnV steel are as follows: tensile strength 785 MPa, yield strength 590 MPa, elongation after fracture 10%, reduction of area 40%, impact absorption energy 55 J. astm a573 grade 70 properties, 20MnV steel has good properties, good strength, toughness and plasticity, good hardenability and machinability. After carburizing, 20MnV steel can be directly quenched without secondary quenching to improve the core structure. The weldability of 20MnV steel is good, but there is temper brittleness at 300-360 ℃ during heat treatment.
Different from astm a573 grade 70 properties, the alloy wear-resistant layer of alloy plate is mainly chromium alloy, and other alloy components such as manganese, molybdenum, niobium, nickel are also added. The carbides in the metallurgical structure are distributed in a fibrous shape, and the fiber direction is perpendicular to the surface. Carbide microhardness can reach HV1700-2000 and surface hardness can reach HRC58-62. Alloy carbides have strong stability at high temperatures, maintain high hardness, and also have good anti-oxidation properties. They are fully used within 500°C.
Our astm a573 grade 70 properties, GB/T 1591-2008 Q460D plates are supplied with thickness up to 100mm. Below is our product stock list: 12*1730*8200, 28.58*2172*12100, 22.23*2181*12000, 28.58*2172*12300, 28.58*2171*12100, 35*2200*3500, 22.23*2182*12200, 28*3720*9400, 22.23*2182*12000, 35*2200*3800, 22.23*2125*12000, 24*3000*8850, 22.23*2075*12000, 14*2405*7610, 28.58*2172*12300, 48*2590*7000, 28.58*2172*11400, 75*1800*3500, 120*2040*9150.
