shipbuilding use GL-D32 weldable steel

Shipbuilding use GL-D32 weldable steel,19Mn6 steel is common carbon manganese low alloy steel produced according to DIN17155. 19Mn6 steel has strict control over harmful elements sulfur and phosphorus in chemical composition. The mass fraction of sulfur and phosphorus in the steel is not more than 0.02%. In addition, vacuum degassing technology is used in smelting, which greatly reduces the gas content in the 19Mn6 steel. 19Mn6 steel has good comprehensive mechanical properties, welding properties and technological properties.

Shipbuilding use GL-D32 weldable steel,After quenching and tempering, 40Cr alloy steel plate and shipbuilding use GL-D32 weldable steel sheet have good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel is good It can be hardened to Ф28 ～ 60mm during water quenching and Ф15 ～ 40mm during oil quenching In addition to quenching and tempering, this steel is also suitable for cyanidation and induction hardening The cutting performance is better When the hardness is HB174 ～ 229, the relative cutting workability is 60% 40Cr alloy steel is suitable for making medium-sized plastic molds,shipbuilding use GL-D32 weldable steel.

Shipbuilding use GL-D32 weldable steel,Both steelmaking and ironmaking are carried out by oxidation-reduction reaction, but there are great differences between them in reaction objects: ironmaking is to reduce iron, while steelmaking is to remove excessive carbon and other impurities in pig iron, so there are relations and differences between them in actual operation. There are three main methods of steelmaking: converter, electric furnace and flat furnace. The converter steelmaking process is most widely used.
