30CrMnSiA steel is a grade of alloy structural steel. The steel has high strength and poor welding performance. It is a high-strength quenched and tempered structural steel with high strength and sufficient toughness after quenching and tempering, and good hardenability. It has good workability, small processing deformation and good fatigue resistance. 30CrMnSiA steel is mostly used to manufacture various important parts with high load and high speed.
In January, 2019, our South Africa customer purchased 669 tons S235J2+N carbon steel plates to use in their tank fabrication project . S235J2 steel, as a non-alloy structural steel grade, is mainly used in structural projects and tanks. J2 symbol -20 temperature impact test. The client required CEV 0.38%, S≤0.01%, 100% UT, Charpy V-notch impact test at-20℃, Z25 for S235J2+N plates. After they receiving the S235J2+N steel plates, the customer are very satisfied with the quality of this batch of shipbuilding material grade LR FH32 plate products.
The cold working performance of shipbuilding material grade LR FH32 plate and so on steel structure engineering steel is good, which can ensure that the steel will not crack or brittle fracture during high-temperature processing, and will not have a great impact on strength, plasticity and toughness due to processing. The durability of shipbuilding material grade LR FH32 plate and so on steel structure engineering steel is good. Durability refers to the service life of steel structure. The main factor affecting the service life of steel is the poor corrosion resistance of steel, followed by the deterioration of mechanical properties of steel under long-term load, repeated load and dynamic load.
As leading EN10025-6 S460QL structural steel plates supplier in China, our company has supplied hundreds of thousands tons S460QL steel plates to clients to assist them finish one after another shipbuilding material grade LR FH32 plate magnificent projects.
