Flat steel is divided into galvanized flat steel, carbon flat steel, stainless steel flat steel, etc. according to the material. Flat steel can be divided into hot-rolled flat steel and forged flat steel according to the forging process. KF36 offshore engineering steel, Hot-rolled flat steel is a potential-rolled long steel with a rectangular cross-section for general use. Forged flat steel is a long steel plate with a rectangular cross section that is forged. Hot-rolled spring flat steel is mainly used to manufacture leaf springs for automobiles, tractors, railway transportation and other machinery. The thickness of the flat steel is 8-50mm, the width is 150-625mm, and the length is 5-15m.
Compared with carbon steel, low alloy steel has many advantages, such as high strength, good plasticity and toughness, good weldability, good cold and hot pressure processing performance, better corrosion resistance, etc. Due to the increase of KF36 offshore engineering steel metal composition, the yield point of low alloy steel structure is higher than that of ordinary carbon steel, so it is light and suitable for structural parts application. The low alloy steel is one of our main products.
The final heat treatment of quenched and tempered alloy steel, KF36 offshore engineering steel is quenching and high temperature tempering. The hardenability of quenched and tempered alloy steel is high, and oil is generally used. When the hardenability is very high, it can even be air cooled, which can reduce the defects of heat treatment. The final properties of quenched and tempered alloy steel depend on tempering temperature. Generally, it is tempered at 500 ℃ - 650 ℃. The required properties can be obtained by selecting tempering temperature. In order to prevent the second kind of temper brittleness, fast cooling (water cooling or oil cooling) after tempering is beneficial to the improvement of toughness.
The chemical composition difference between KF36 offshore engineering steel, 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 KF36 offshore engineering steel, 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.
