What are the properties of EN 10083-3 30MnB5 quenched and tempered plate
Our company is China's 10th largest supplier & Exporter of stainless steel, carbon steel plate and section, alloy steel plate and pipes. We are specialized in stocking & distributing various Stainless Steel, carbon steel plates, EN 10083-3 30MnB5 quenched and tempered plate angle steel, H beam steel to worldwide for specific & urgent requirements. We have a fully advanced and modernized warehouse that stores tonnes of our value-adding EN 10083-3 30MnB5 quenched and tempered plate products, which we source out from the mills that are compliant with the universal guidelines for plate production.
High weather resistance structural steel Q295GNH, Q355GNH adds a small amount of alloying elements such as Cu, P, Cr, Ni, etc. to form a protective layer on the basic surface of the metal to improve the steel with atmospheric corrosion resistance. High weather resistance structural steel is mainly used in the structure of vehicles, containers, buildings, towers or other structural parts. Compared with welded structural steel EN 10083-3 30MnB5 quenched and tempered plate, it has better atmospheric corrosion resistance.
The EN 10083-3 30MnB5 quenched and tempered plate, wear-resistant steel plate has complete specifications and many varieties, and has become a commercial series. The thickness of the wear-resistant alloy layer is 3-20mm. Wear-resistant steel plates are divided into three types: ordinary type, impact resistant type and high temperature type. Wear-resistant steel plate can be cut, bent or crimped, welded and punched, and it can be processed into various parts that can be processed by ordinary steel plate. The cut wear-resistant steel plates can be tailor-welded into various engineering structural parts.
Generally speaking, the higher the strength of EN 10083-3 30MnB5 quenched and tempered plate, weathering steel, the greater the hardness, while the plasticity and toughness will decrease. When the carbon content of weathering steel exceeds 1.2%, the hardness will increase, but the strength will not increase, but will decrease. Resilience will also decline quickly. When the carbon content is high, the cementite increases and forms network distribution, which weakens the connection between grains and makes the mechanical properties of steel worse.
The chemical composition difference between EN 10083-3 30MnB5 quenched and tempered plate, Q235B and 20# steel is as follows: The chemical composition of 20# steel: C: 0.17-0.23%, Si: 0.17-0.37%, Mn: 0.35-0.65%, Cr: ≤ 0.25%, Ni: ≤ 0.30%, Cu: ≤ 0.25%. Chemical composition of Q235B steel: C: ≤ 0.20%, Si: ≤ 0.35%, Mn: ≤ 1.40%, P: ≤ 0.045%, S: ≤ 0.045%. The difference of mechanical properties between EN 10083-3 30MnB5 quenched and tempered plate, Q235B and 20# steel is as follows: The mechanical properties of 20# steel: tensile strength 410 MPa; yield strength 245 MPa; elongation after fracture: 25; reduction of area: 55; no impact. Q235B steel mechanical properties: tensile strength 370-500 Mpa; yield strength: ≥ 235 Mpa; elongation after fracture: 25; impact absorption energy: 27J.
