The standard of GB 713 15CrMoR steel is applicable to the boiler and its accessories and the pressure partsof normal pressure vessel for 3 mm thickness steel plates.
GB 713 15CrMoR steel Specifications (T*W*L):
3--200mm * 1200--3400mm * 3000--18000mm
GB 713 15CrMoR steel Delivery Condition:
Plates are normally supplied in the tempered or normalized condition.
15CrMoR belongs to Cr-Mo series steel, now is currently widely used in heat-resisting steel and hydrogen resistant steel. As a result of the low carbon steel by adding Cr, Mo and other alloying elements, greatly improving the overall performance of steel. Such as good high temperature mechanical properties, high temperature oxidation resistance, corrosion resistance, good toughness, process performance and weldability, it is widely used in the manufacture of petrochemical, coal conversion, nuclear power, turbine cylinder, thermal power and other conditions of use Harsh, corrosive medium complex large equipment.
