Steel API 5L X70 (L485) PSL2 Plate physical properties

In recent years, in line with the development trend of iron and Steel API 5L X70 (L485) PSL2 Plate steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which Steel API 5L X70 (L485) PSL2 Plate are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.

15Mo3 steel manufacturing method: adopt oxygen top blown converter method, 182 open hearth method or 3666 to smelt in 3769 electric furnace. After negotiation with the customer, other equivalent methods can also be adopted.15Mo3 steel is used for heating surface pipes, economizers, superheaters, reheaters, etc. of high-pressure boilers Steel API 5L X70 (L485) PSL2 Plate (working pressure is generally above 9.8MPa, working temperature is between 450 ℃ ~ 650 ℃).

Alloy steel plates that have the ability to develop an extensive range of hardness and strength. Alloying elements and thermal treatments, such as quenching and tempering, greatly influence the hardness and strength of the steel. Welding and forming of this steel plate Steel API 5L X70 (L485) PSL2 Plate should be avoided. It is best utilized wherever high resistance to fatigue and or impact is necessary. We can supply ASTM, JIS, DIN and GB various standards alloy steel grades.

The blanking of the structural steel plate is first to find 90 degrees, and then use a tape measure and a powder line to draw the cutting range. According to the thickness of the carbon steel plate plus the cutting allowance, drilling is required. For the deep processing of Steel API 5L X70 (L485) PSL2 Plate structural steel sections or profiles: First use a square ruler or a curved ruler to find 90 degrees, and then use a square ruler or a ruler to cut the line and add the cutting margin to the hole.

Chemical composition of 65Mn steel: C 0.62-0.70, Si 0.17-0.37, Mn 0.90-1.20, Cr ≤ 0.25, Ni ≤ 0.30, Cu ≤ 0.25. 65Mn steel mechanical properties: tensile strength: ≥735 Mpa, yield strength: ≥430 Mpa, elongation after fracture: ≥9%, reduction of area: 30%, impact absorbed energy: no impact. Steel API 5L X70 (L485) PSL2 Plate, 65Mn steel has high strength, high hardenability, less decarburization tendency, overheat sensitivity, easy to produce quenching cracks and temper brittleness. 65Mn steel is used for making various flat and round springs, leaf springs, spring rings, valve springs, steel wire cold coil springs, clutch springs of light trucks and cars.

Customer first, reputation first, high-quality and perfect after-sales service is the extension of our product value and an important guarantee for the interests of customers. The purpose of our Steel API 5L X70 (L485) PSL2 Plate service quality management system is to establish and constantly improve a scientific, reasonable and efficient service quality management system, and complete the after-sales service quality guarantee work of customers fairly, accurately and timely, For our company's Steel API 5L X70 (L485) PSL2 Plate customer service to establish a good, comprehensive, full service system.
