shipbuilding material grade LR FH32 plate material heat treatment

Steel plate is divided into rolling, hot rolling and cold rolling. The width of the thin plate is 500 ~ 1500 mm; the width of the thick plate is 600 ~ 3000 mm. Thin plates are classified according to steel types, including ordinary steel, steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, shipbuilding material grade LR FH32 plate, bearing steel, etc .; according to use, there are ship plates, pressure vessel plates, atmospheric corrosion-resistant steel plates, bulletproof steel plate.The shipbuilding material grade LR FH32 plate plate products have passed the EU CE certification, and have been recognized by China, France, the United States, the United Kingdom, Germany, Italy, Japan, South Korea and other eight classification societies for high-strength ship plates. The steel strand products have passed the United States (PTI) certification. The shipbuilding material grade LR FH32 plate products enjoy a high reputation in the domestic and foreign markets. The products are applied to national key projects and sold to 37 countries and regions such as EU, Middle East, Southeast Asia and America.As the thickness and hardness of shipbuilding material grade LR FH32 plate increase, the tendency to crack at the cutting edge increases. In order to prevent the shipbuilding material grade LR FH32 plate from cutting cracks, preheating should be carried out before shipbuilding material grade LR FH32 plate cutting. Special attention should be paid to preheating to make the entire shipbuilding material grade LR FH32 plate interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole shipbuilding material grade LR FH32 plate cannot be preheated, the partial preheating method can be used instead.The addition of Ca element in steel such as shipbuilding material grade LR FH32 plate can refine grain size, partly desulphurize and change the composition, quantity and morphology of non-metallic inclusions. It is similar to that of adding rare earth in steel. It can improve the corrosion resistance, wear resistance, high temperature and low temperature resistance of steel, improve the impact toughness, fatigue strength, plasticity and welding performance of the steel, and increase the cold heading, shock resistance, hardness and contact endurance strength of the steel.We have a professional after-sales department to collect all information related to customers, so as to make relevant treatment in time according to the information, and file it; guide the user's product use methods and precautions; coordinate with the sales department, visit customers regularly, understand the customer's use and new requirements, and make a customer visit record; When communicating with customers, they should be enthusiastic and careful to understand the situation of product problems and put forward solutions
