16Mo3 steel is a kind of European boiler steel plate. 16Mo3 is different from other raw materials when welding. It must be preheated first, and the weld should be kept for about 30 minutes after the welding is completed. A709 grade 36 bridge steel plate, 16Mo3 manganese steel is also an important alloy element steel, it is an important hardenability element. 16Mo3 alloy is a material used at elevated operating temperatures, such as weldable steel in the manufacture of industrial boilers and stainless steel pressure vessels in the petroleum, natural gas and chemical industries.
After quenching and tempering, 40Cr alloy steel plate and A709 grade 36 bridge steel plate sheet have good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel A709 grade 36 bridge steel plate 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.
The cold bending method is mainly used to produce cold-formed section steel and welded pipe. The cold bending method is to bend the steel strip or steel plate into various cross-section shapes by the cold bending machine in the cold state. If the A709 grade 36 bridge steel plate steel pipe is bent into a circular, square or other hollow shape and welded by a proper welding method, it is a welded pipe. The advantages of cold bending: first, the cold-formed section steel is light in weight and large in bearing capacity, and it can save metal by replacing the hot-rolled section steel; second, it can produce all kinds of A709 grade 36 bridge steel plate extremely thin, extremely wide and complex section steel which can not be produced by hot rolling.
our company is a professional ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates steel exporter and a steel Stockist in china.
