We recieved new order about differences between a573 grade 70 and a588 grade K steel 3mm thickness and so on dimension ABS grade A shipbuilding steel plates. It is not easy to find 3mm thickness shipbuilding steel plates supplier. The order was put to other supplier before, but the customers was informed not able to supply 3mm thickness differences between a573 grade 70 and a588 grade K steel shipbuilding steel plates with ABS certificate. This was disappointed and the customer had to withdraw the order. After a lot of investigation and recommendation, the customer finally find us and we fully have the ability to supply this batch of shipbuilding steel plates according to their requirements.
The acicular ferrite pipeline steel can inhibit the formation of polygonal ferrite, promote the acicular ferrite transformation, and improve the precipitation strengthening effect of carbon and niobium nitride by adding molybdenum to reduce the transformation temperature of polygonal ferrite, so as to improve the strength of steel and reduce the ductile brittle transition temperature. The differences between a573 grade 70 and a588 grade K steel, tempered sorbite pipeline steel adopts the heat treatment process of quenching and tempering. The tempered sorbite structure is formed to meet the comprehensive requirements of thick wall, high strength and sufficient toughness.
