What is ASTM equivalent of a204 grade b steel properties and their difference

As a leading hot rolled plate mill in China, We manufacture and export carbon steel and alloy a204 grade b steel properties steel plates in different sizes and of different thickness. We have an adept and proficient team of professionals in addition to our responsive staff that is ever alert for any customer queries and requisites. If you are experiencing difficulty in selecting the correct a204 grade b steel properties steel plates for your business, we have a team of experts who can give you the best advice on steel plates, a significant contributor that can flourish your business.

20# steel plate is a high-quality low-carbon carbon steel plate, cold extruded, carburized and hardened steel. a204 grade b steel properties, 20# steel has low strength, good toughness, plasticity and weldability. The tensile strength is 253-500MPa, and the elongation is ≥24%. 20# steel performance is basically similar to 15# steel, but the strength is slightly higher. The cold-drawing or normalizing state of the cutting process is better than the annealing state. 20# steel is used to manufacture various mechanical parts with high toughness under hot rolling or normalizing state, which require high toughness.

a204 grade b steel properties, Q215A steel belongs to carbon structural steel. Q215A steel does not contain specially added alloy elements. a204 grade b steel properties, Q215A steel is mainly used in construction and engineering structures. Chemical composition of Q215A steel: C: ≤ 0.15, Si: ≤ 0.30, Mn: ≤ 1.20, P ≤: 0.045, S ≤: 0.050. Q215A steel has low carbon and manganese content. Q215A steel strength is slightly higher than Q195 steel strength. a204 grade b steel properties, Q215A steel has good plasticity, good toughness, weldability and process performance. Q215A steel is mainly used in plant building, bridge components, tower, derrick and vehicle and ship manufacturing components.

Hydrogen (H) is the most harmful element in general steel such as a204 grade b steel properties. Hydrogen dissolved in steel will cause hydrogen embrittlement, white spots and other defects. Hydrogen, like oxygen and nitrogen, has very little solubility in solid steel. It dissolves into liquid steel at high temperature, and accumulates in the structure without time to escape when cooling, forming high-pressure micro pores, which greatly reduce the plasticity, toughness and fatigue strength of steel, and even cause cracks and brittle fracture in severe cases. "Hydrogen embrittlement" mainly occurs in martensitic steel, but not very prominent in ferrite steel, and generally increases with hardness and carbon content.

Structural steel is a category of steel construction material that is produced with a particular cross section or shape, and some specified values of strength and chemical composition. a204 grade b steel properties, Structural steel plates are normally supplied in the as-rolled condition. Our structural steel plate are supplied with thickness range 3mm to 350mm. The plates may be ordered normalized or stress relieved, or both. steel plates shall be normalized. steel plates and sheets shall be quenched and tempered.

We are known as a204 grade b steel properties leading manufacturers, suppliers and exporters in the market all over the world. We engage in providing a wide range of plates which are accurately mass produced by using the best quality of parts which gives maximum durability and dependability. The most important thing to know as a potential customer of IRON&STEEL is that we a204 grade b steel properties stock, processing service, and distribute all of the popular grades of carbon steel plate, alloy steel, shipbuilding steel and boiler steel. Welcome to come China and visit our factory.
