Cangzhou Bohai Pipe Co., Ltd. specializing in the production of alloy steel elbow 12cr1mov Key Features: This steel and alloy steel elbow quote 12CrMoV than steel, has a higher oxidation resistance and heat resistance. This steel creep rupture strength and ultimate value is very close and has a high plasticity in the case of persistent tension; the process of alloy steel with good weldability steel elbow, but before welding to be preheated to 300 ℃, welding After the required stress relief treatment. High-pressure, high pressure, sub-critical power plant boiler superheater header and main steam pipe widely used steel. 580 ℃ still has high thermal strength and oxidation resistance, a higher durable plastic. The production process is relatively simple, good weldability sell steel elbow, but more sensitive to normalizing the cooling rate. 580 ℃ long-term use will produce pearlite ball. Cangzhou Bohai Pipe Co., Ltd. specializing in the production of steel line pipe elbow: is the axis of the oil out of the ground, air or water, through a pipeline to transport pipe to the oil and gas industry companies.
