Which steel grade is equivalent to astm a514 grade b equivalent
Based on the main astm a514 grade b equivalent business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and heavy plate, hot rolled coil, section steel, steel tube, etc., which are widely used in automobile, oil, railway, bridge, construction, electricity, transportation, machinery, shipbuilding and other important fields. Our steel astm a514 grade b equivalent products are exported to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.
With the development of pipeline steel plate technology and the advancement of welded pipe forming and welding technology, the application scope of pipeline welded pipe is gradually expanding, especially in the range of large-diameter group spacing. Occupying a leading position in the field of line pipes has restricted the development of stainless steel seamless line pipes. In 2004, the output of astm a514 grade b equivalent seamless line pipes was about 400,000 tons, with steel grades including X42-70, and varieties of onshore line pipes and subsea line pipes.
For a ship, the choice of medium and thick ship plate is very important, it is an important part of the ship frame. The pressure bearing capacity of astm a514 grade b equivalent, medium and thick ship plates is very strong. Secondly, because it is a ship plate, it must be driven in water, so of course the corrosion resistance is better, otherwise it will bring danger to buyers. Moreover, the service life of the ship will be increased. Regular inspection of the ship plate can ensure the safety of sailing. You can also know whether the ship plate is defective, so you don't have to worry about water seepage when you sail.
The acicular ferrite pipeline steel can inhibit the formation of polygonal ferrite, promote the acicular ferrite transformation, and improve the precipitation strengthening effect of carbon and niobium nitride by adding molybdenum to reduce the transformation temperature of polygonal ferrite, so as to improve the strength of steel and reduce the ductile brittle transition temperature. The astm a514 grade b equivalent, tempered sorbite pipeline steel adopts the heat treatment process of quenching and tempering. The tempered sorbite structure is formed to meet the comprehensive requirements of thick wall, high strength and sufficient toughness.
astm a514 grade b equivalent, 27SiMn material has high strength and wear resistance, high hardenability, medium plasticity during cold deformation, good machinability and fair weldability. It is mostly used after quenching and tempering, and can also be used in normalizing or hot rolling state. 27SiMn material chemical elements: C: 0.24-0.32, Si: 1.10-1.40, Mn: 1.10-1.40. 27SiMn material mechanical properties: tensile strength 980 MPa; yield strength: 835 MPa; elongation after fracture: 12%; impact energy: 39J. 27SiMn material can be used to make hot stamping parts with high toughness and high wear resistance, which do not need heat treatment or normalizing, such as tractor track pins.
