How to identify inferior EN10025-4 S460ML steel

The company produces seamless steel pipes such as GB, ASTM, etc. all year round, including low and medium pressure boiler steel pipes, high pressure boiler steel pipes, EN10025-4 S460ML steel seamless steel pipes for ships and petroleum cracking EN10025-4 S460ML steel steel pipes, Seamless steel pipe, oil sleeve steel pipe, pipeline steel pipe, hollow sucker rod, common fluid steel pipe, structural pipe, kauden steel pipe, seawater corrosion-resistant titanium pipe and imported alloy steel pipe are used for high-pressure fertilizer equipment. The products are widely used in petroleum, chemical, electric, boiler, ship, machinery and other industries, and have been sold all over the country. Many EN10025-4 S460ML steel products have been exported to the Middle East, India, Southeast Asia and Europe and America.

ASTM A213 T9 seamless pipe is ferritic and austenitic alloy-steel boiler, superheater, and heat-exchanger tubes. BBN steel company supplies Cr-Mo low alloy steel grades of T2, T5, T5b, T5c, T9, T11, T12, T17, T21, T22, T23, T24, T36, T91, T92, T122, and T911. The tubing sizes and thickness usually furnished to this specification are 1/8″(3.2 mm) in inside diameter to 5″(127 mm) in outside diameter and 0.015″ to 0.500″(0.4-12.7 mm) in minimum or average wall thickness.

The main characteristics of EN10025-4 S460ML steel, 12Cr1MoV alloy steel plate are as follows:Compared with 12CrMoV steel, 12Cr1MoV alloy steel plate has higher oxidation resistance and thermal strength. The creep limit of 12Cr1MoV steel is close to the stress rupture strength, and it has high plasticity under the condition of long-term tension. The process and weldability of 12Cr1MoV steel are good, but it needs to be preheated to 300 ℃ before welding, and stress relief treatment is required after welding.

The effect of elements in the wear plate on high temperature temper brittleness: chromium, manganese, nickel, silicon, etc. play a role in promoting, while molybdenum, tungsten, titanium, etc. play a retarding role, and carbon also plays a role in promoting. Generally, EN10025-4 S460ML steel, carbon wear-resistant steel plates are not sensitive to high temperature tempering brittleness, while binary or multi-element alloy steels containing chromium, manganese, nickel, and silicon are very sensitive. The degree of sensitivity varies depending on the type and content of alloy elements.

According to GBT3077, 42CrMo steel chemical composition should be within the range (%): 42CrMo carbon content is 0.38-0.45 (C), Silicon content is 0.17-0.37 (Si), Manganese content is 0.50-0.80 (Mn), Chrome content is 0.90-1.20 (Cr), Molybdenum content is 0.15-0.25 (Mo). The high Cr content contrivutes to high strength of 42CrMo steel, with min. yield strength of 930 Mpa, and min. tensile strength of 1080 Mpa. The common heat treatment for EN10025-4 S460ML steel, 42CrMo steel is quenching and tempering.
