Influence of tempering temperature on properties of S420ML steel mechanical properties

The company has a group of mature steel plate production and processing line construction and production management experience. In addition, the company has professional and technical personnel. BBN steel is a modern enterprise integrating scientific research and development, production processing, sales and service. The company now has finance department, production department, sales team, technical department, quality control department, logistics department and after-sales service team. At the same time, it also adheres to international standards and adheres to the international line.

27SiMn steel plate has high strength and wear resistance, high hardenability, good machinability, moderate cold deformation plasticity and weldability. In addition, the toughness of 27SiMn steel does not decrease much during heat treatment, but it has quite high strength and wear resistance, especially when water quenching still has high toughness; but this steel is highly sensitive to white spots and has temper brittleness during heat treatment. Tendency and sensitivity to overheating.

There are various weather resistant steel materials in the world. Their thickness ranges are distinct. For JIS G3125 weathering steel sheet, typical grades are SPA-H / SPA-C, the max. thickness is 16mm. For TBT 1979 weather resistant steel sheets, typical grades are 09CuPCrNi-A / 05CuPCrNi, the max. thickness is 20mm. For EN 10025-5 steel, typical grades are S355J0WP / S355J2WP / S355J0W /S355J2W, the max. thickness is 100mm. The max. thickness for S420ML steel mechanical properties, ASTM A588 steel plate is 200mm. And the max. thickness for ASTM A242 steel plate is 100mm.

High-temperature boiler steel plates such as 15CrMoR plate, 12Cr1MoVR steel plate, ASME SA387 grade 22 steel, A387 Gr 91 boiler steel, ASME SA1017 Gr 23, SA1017 Gr 911, SA1017 Gr 122 steel, S420ML steel mechanical properties, must have features of:Sufficient high temperature durability and durable plasticity;Good high temperature tissue stability;Good high temperature oxidation resistance (heat resistance);Good hot and cold processing technology (mainly refers to cold bending deformation and weldability), etc.

In addition to quality assurance, service is also important for the competition of steel suppliers. All the after-sales service personnel of the company have received professional training and assessment. The steel products supplied by our company enjoy the life-long quality problem replacement service. In the process of using our steel S420ML steel mechanical properties products, if there is any problem, just contact us in time, and our after-sales service personnel will look for countermeasures and solve the problem with you as soon as possible.

Our focus on quality has helped us create an efficiently organised production system, which can supply large-scale piping orders as well as tailor-made orders for smaller clients. We have also created a sales and support network which stretches from Asia to Europe, UAE, South Africa and South America.
