Introduction: high quality carbon steel, craft pure rolling, no oxidation state) NBK heat treatment (brightness, nondestructive testing, steel tube wall with special equipment and pressure flushing, scrub oily-type rust on steel processing, both for block as dustproof.
Main features: the internal and external wall of steel and high precision and surface, heat treatment, inner tube without oxidation layer of high voltage withstand cleanness, steel, cold bending deformation, flaring, squash, no crack can make various complex mechanical deformation and processing. Colour: white with steel, high metal luster.
Main purpose: automobile use steel tube, the precision and surface has high requirements of users.
Main materials and mechanical properties:
This company USES the raw materials for the main production St35, Shanghai baosteel St37.4 (10), St45 (20 # # # 35), St55 (), Ck45 (45 #), St52 (16Mn), etc.
This company produces the mechanical properties of the steel, steel excellent performance, high impact, can bear, especially suitable for hydraulic machinery and auto industry. Any Angle steel can be cold bending deformation, flaring, no crack, squash with the need for bending deformation processing various industries.
Surface quality
Steel pipe inside and outside surface cleaning, no oxidation layer, no crack, folding, rolling, scar, grouting, grain,.
With the use of pipe manufacturing methods and treatment methods of surface should state (e.g., scratches, bump, groove depth), but its not super too 0.025 mm (the DIN2391 require higher standards),
