4mm thick Q235B carbon steel plate sheet

Q235B carbon steel plate sheet, 40Cr material is a common machinery manufacturing steel under GB/T 3077-2015 standard. After tempering, it has good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel is good. It can be hardened to Ф28-60mm during water quenching and Ф15-40mm during oil quenching. The cutting performance is better, when the hardness is HB174 -229, the relative cutting workability is 60%.

The main advantage of 20CrMo alloy steel plate is reflected in its various physical and chemical properties. For 20CrMo alloy plate, the main component is alloy, and the physical and chemical properties of alloy Q235B carbon steel plate sheet are generally, a single metal is better, and its performance is stronger. The main features of 20CrMo alloy steel plate are high precision, rigidity, high temperature and high pressure resistance, not easy to corrode and other characteristics.

Quenching and tempering (QT) is a double heat treatment process of quenching and high temperature tempering. In general, medium carbon steel and medium Q235B carbon steel plate sheet carbon alloy steel often need quenching and tempering treatment. Quenching and tempering can make iron and steel parts obtain a good combination of strength and toughness, with high strength, excellent toughness, plasticity, cutting performance, etc. Some Q235B carbon steel plate sheet alloy steel or low alloy steel must be quenched and tempered to obtain good comprehensive properties. These steels can also be called quenched and tempered steels.

The high strength Q235B carbon steel plate sheet low alloy steel, which is shorten as HSLA steel, is one of our main products. We have professional team to serve you. For any demands or questions about HSLA steel, for example, ASTM A572 grade 50 chemical composition, difference between S355JR and S355J2, mechanical properties of Q235B carbon steel plate sheet ST52 steel, Q345B tensile strength, Q345D steel ASTM equivalent, HSLA steel price etc. , please do not hesitate to contact us and consult.
