Rolling process of hardox 400 sheet tensile strength
HARDOX 400 sheet tensile strength, Q195 and Q235 belong to carbon structural steel, which are mainly used in buildings and engineering structures such as workshops, bridges, ships, etc. Of course, there are many differences between Q195 steel and Q235 steel. 1. Different components. The chemical composition of Q195 steel: C ≤ 0.12, Si ≤ 0.30, Mn ≤ 0.50, P ≤ 0.035, S ≤ 0.040. The chemical composition of Q235 steel: C ≤ 0.22, Si ≤ 0.35, Mn ≤ 1.40, P ≤ 0.045, S ≤ 0.050. 2. The prices of HARDOX 400 sheet tensile strength, Q235 steel is higher than that of Q195 steel. 3. The mechanical properties of Q195 and Q235 steel are different. The tensile strength of Q195 steel is ≥390 MPa, yield strength is ≥195 MPa, and the elongation is ≥ 30%. The tensile strength of Q235 steel is 490 MPa, yield strength is ≥235 MPa, and the elongation is 23%.
Boiler steel refers to the special steel used to manufacture pressure components of steam boilers, such as steam drums. The boiler steel mainly means boiler steel plates and seamless boiler steel pipes. Boiler components not only bear pressure loads but are also heated by direct fire, so the requirements on the chemical composition and mechanical properties of boiler steel, HARDOX 400 sheet tensile strength are strict. In the chemical composition of boiler steel, HARDOX 400 sheet tensile strength, sulfur and phosphorus are strictly controlled. Tensile strength, yield point, elongation, impact energy value and 180 ° cold bending are required to be tested in boiler steel mechanical properties. In addition, strain aging impact test is also required for boiler steel. The quality control of boiler steel is slightly higher than that of pressure vessel steel.
Titanium microalloying is an element of HARDOX 400 sheet tensile strength strengthening complex with carbon and nitrogen. The addition of micro amount of titanium in the steel can fix almost all nitrogen and part carbon in the steel, so as to eliminate the strain aging phenomenon and improve the aging impact performance of the steel. At the same time, it can refine the grains and change the morphology of the compounds. According to the atomic weight ratio of Ti and N in HARDOX 400 sheet tensile strength tin formula (Ti = 3.4n), the content of Ti in steel should be controlled between 0.015 and 0.025%. Generally, the amount of ferrotitanium added to each ton of steel is 1kg.
