API 5L Gr. A is mainly used for steel of large diameter pipeline. S355ML mechanical properties, API 5L Gr. A is mainly used for pressure liquid transportation, oil, natural gas, water and other liquid transportation, oilfield engineering, pipeline engineering, construction, steel pipe and oil and gas engineering using pipeline.

If the chromium content in S355ML mechanical properties alloy steel reaches about 12%, dense chromium oxides will be formed on the surface of the steel, which will greatly improve the corrosion resistance of steel in oxidizing media. Chromium, aluminum, silicon and other elements can improve the oxidation resistance of steel and the corrosion resistance of high-temperature gas, but excessive aluminum and silicon will deteriorate the thermoplasticity of steel.

40Cr grade under GB/T 3077-2015 standard is a alloy steel bar material. S355ML mechanical properties, 40Cr alloy chemical composition (C: 0.37 ~ 0.44, Si: 0.17 ~ 0.37, Mn: 0.50 ~ 0.80, Cr: 0.80 ~ 1.10, Ni: ≤0.30, P: ≤0.030, S: ≤0.030, Cu: ≤0.30, Mo: ≤0.10). Heat treatment: First quenching heating temperature (℃): 850; coolant: oil; Temperature heating temperature (℃): 520. 40Cr steel tensile strength (σb / MPa): ≥980. Yield point (σs / MPa): ≥785

In the process of S355ML mechanical properties steel transportation, enterprises often use railway transportation, highway transportation, water transportation and other ways to transport. According to the cargo owner's requirements on the timeliness of the goods and the different transportation routes, our company will choose S355ML mechanical properties different modes of transportation. According to the specific needs of customers, or specify the mode of transportation.

The high strength S355ML mechanical properties 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 S355ML mechanical properties ST52 steel, Q345B tensile strength, Q345D steel ASTM equivalent, HSLA steel price etc. , please do not hesitate to contact us and consult.
