Why is ASTM A514 steel material more expensive?

Beijing machining center has more than 1000 employees, including 360 technicians, 28 engineers, 6 senior welders, 15 professional welders, 52 bachelor's degree, 3 doctor's degree, and 8 R & D team. It is a professional ASTM A514 steel material production team combining theory and practice. With an annual output of 80000 tons, looking forward to the future, our company continues to strengthen the advantages of ASTM A514 steel material leading suppliers in the four steel fields of steel plate, steel pipe, stainless steel and special steel.

We can supply profiled plate in a range of grades in thicknesses up to 400mm and dimensionally we can cut up to 24 meters in length and 5 meters wide with flame cutting, plasma cutting and laser cutting service. This capability is backed by an in-house CAD team, capacity that enables us to work to short lead times and an established delivery network that ensures you receive the steel ASTM A514 steel material products when you need it.

Difference between Q345R boiler vessel plate and ordinary Q345 plate, ASTM A514 steel material:Q345R boiler vessel plate is pressure vessel steel, Q345 plate is low alloy steel.Q345R boiler vessel plate generally requires flaw detection and positive deviation, while Q345 plate generally has lower requirements.In terms of performance, Q345R boiler vessel plate and Q345 plate are of the same level. However, due to high requirements, they can not be mixed in general.Generally, the requirement of Q345R boiler vessel plate is higher than Q345 plate, ASTM A514 steel material.

ASTM A514 steel material, S355j2g3 steel plate is a kind of main atmospheric corrosion-resistant steel, s355j2g1w steel plate is a kind of weathering structural steel, its mechanical properties are similar to s355j2g2. By adding CR, Cu and Ni, the oxide layer is firmly attached to the workpiece surface. This oxide layer prevents further corrosion of the steel.

A131 EH36 steel is high strength marine grade hull structural steel. Its yield strength is no less than 355Mpa, tensile strength is 490-620 Mpa, and elongation is 19% min. ASTM A514 steel material, EH36 steel strength is close to S355 steel. However, EH36 steel is shipbuilding steel, while S355 steel is carbon structural steel, and can not be certified by classification society. That is to say, S355 steel is not allowed to be used for ship building when there is certificate requirement. A131 EH36 steel is widely used to build ships working in low temperature water.

The boiler steel plates are among our main products. Other than standard size boiler steel plates, we also provide ASTM A514 steel material cutting, bending and so on processing to change plate size and shape according to your requirements. Welcome to consult us about ASTM A514 steel material ASTM A204 grade B properties, SA 516 gr 70 temperature range, ASTM A285 grade C chemical composition, boiler steel price and so on questions and ask for offer.

Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel ASTM A514 steel material plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.
