What is the difference between astm a573 grade 58 and ordinary strength steel

In recent years, in line with the development trend of iron and astm a573 grade 58 steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which astm a573 grade 58 are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.

Steel is the main raw material for shipbuilding and marine engineering structure construction, accounting for 20% ~ 30% of the construction cost of hull and marine engineering. The steel astm a573 grade 58 products involved mainly include steel plates and section steel (marine bulb flat steel, H-beam, angle steel, etc.), casting and forging steel and supporting welding materials, etc. Among them, the amount of steel consumed for hull construction accounts for about 60% of the total ship mass, and sheet metal accounts for about 88%.

The alloy steel seamless pipe is a kind of product developed on the basis of traditional seamless steel pipe. Some characteristics of the astm a573 grade 58, alloy steel seamless pipe are also great progress and optimization based on the traditional seamless steel pipe products. Alloy steel seamless pipe is a kind of high performance seamless pipe. In industrial production, seamless pipe is usually used in pipeline engineering which needs to bear greater pressure.

With the increase of carbon content in the steel material, the yield point and tensile strength increase, but the plasticity and impact decrease. When the carbon content is more than 0.23%, the welding performance of the steel material becomes worse. Therefore, the carbon content of low alloy structural steel used for welding is generally less than 0.20%. The high carbon content can also reduce the atmospheric corrosion resistance of steel material, and the high carbon steel in the open air is easy to rust; in addition, carbon can increase the cold brittleness and aging sensitivity of astm a573 grade 58 etc. steel material.

T11 steel is a steel grade produced according to American Standard ASTM A213. T11 steel is used for boiler, superheater and heat exchanger tubes with minimum wall thickness. Chemical composition of ASTM A213 T11 steel: C 0.05-0.15, Si 0.50-1.00, Mn 0.30-0.60, P, S ≤ 0.025, Cr 1.00-1.50, Mo 0.44-0.65. Mechanical properties of ASTM A213 T11 steel: tensile strength ≥ 415 Mpa, yield strength ≥ 170 Mpa, elongation ≥ 30%. The main ASTM A213 steel pipe grades are A213 T11, A213 T12, A213 T22, astm a573 grade 58, etc.

The company adheres to the business philosophy of "good quality, customer first, honesty and trustworthiness", and strives to provide customers with high-quality astm a573 grade 58 products and excellent services. Our company's products astm a573 grade 58 are widely used in petroleum, chemical, power station, boiler and other industries, mainly used in reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied gas tanks, nuclear energy reactor pressure shells and other equipment.

After-sales service is an important part of measuring a product good or not. After sales service can't be ignored. Good service can really make consumers feel relieved. We have always done a good job in after-sales service, so as to bring consumers a better reference when purchasing and a better experience during use of our steel materials. We will call back and follow up the performance of our steel products regularly.
