Product Description:
GNEE supplies 3 major types of low alloy steel plate for structural purposes(hgih strenght and medium strength): 16Mn, 15MnVN and low-carbon bainitic steel. Main standard include GB/T1591-94, JIS G3106, JIS G3101, DIN17100, ASTM A572M, EN10025, etc.
16 mn is a major steel grade of high strength low alloy steel plate in most industries, The consumption of this type is very large. Its intensity is higher than the ordinary carbon structural steel Q235 by 20% ~ 30%, atmospheric corrosion resistance by 20% ~ 38%.
15 MNVN is mainly used as medium strength steel plate. It is featured with high strength and toughness, good weldability and low temperature toughness and is widely used in the manufacture of Bridges, boilers, ships and other large structures.
Strength level is above 500 Mpa, low carbon alloy steel plate is not able to meet the requirements, low carbon bainite steel plate is developed. Added with elements such as Cr, Mo, Mn, B, to help steel plate in forming bainite organization, makes it with higher intensity, plasticity and good welding performance, it's mostly used in high pressure boiler, pressure vessel, etc.
Alloy steel plate is mainly used for building bridges, ships, vehicles, boiler, pressure vessel, oil pipelines, large steel structure.
Performance requirements:
High strength: its yield strength is more than 300 mpa.
High resilience: requirements elongation is 15% ~ 20%, the impact toughness at room temperature is greater than 600 kj/m ~ 800 kj/m. For large welded components, but also requires a high fracture toughness.
Good weldability and cold forming performance.
Low ductile-brittle transition temperature.
Good corrosion resistance.
