S355J0 steel is a low alloy structural steel. We can supply S355J0 structural steel plates up to 400mm, with a minimum yield strength 355MPa when plate thickness less than 16mm, min. yield strength 345MPa when plate thickness range 16mm to 40mm. Without any special rolling or heat treatment for S355J0 steel plate and sheet, SPA-H section steel, the abbreviated designation of this delivery condition shall be AR (As rolled).

As the thickness and hardness of SPA-H section steel increase, the tendency to crack at the cutting edge increases. In order to prevent the SPA-H section steel from cutting cracks, preheating should be carried out before SPA-H section steel cutting. Special attention should be paid to preheating to make the entire SPA-H section steel interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole SPA-H section steel cannot be preheated, the partial preheating method can be used instead.

DIN 17100 St37-2 steel plate belongs to the carbon and low alloy high strength steel plate. We can supply the different sizes of SPA-H section steel, DIN 17100 St37-2 steel plate. And the rolling size of DIN 17100 St37-2 steel plate is following: the thickness range is 1.2-600mm, the width range is 1220-4200mm, and the length range is 5000-18000mm. Also note that the DIN 17100 St37-2 steel coil thickness should not exceed 25 mm.

As a leading international steel supplier, we have two warehouses, close to Tianjin port and Shanghai port. This superior geographical location effectively saves the domestic transportation cost and greatly improves our service level. At the same time, it also shortens our delivery time and provides more convenience for customers.
