Though the tariffs were supposed to help the domestic RINA EH36 hull steel plate steel companies, history has shown that tariffs are only a short term fix. Though the domestic mills are operating at over 80% of their capacity, which is an impressive rise over a year ago, steel still remains a global commodity with a RINA EH36 hull steel plate global market. Even with the current level of capacity utilization, the US still needs to import about 30 million tons of steel.

Quenching is a common heat treatment process. It is the metal heat treatment process in which the RINA EH36 hull steel plate metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between RINA EH36 hull steel plate strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.

RINA EH36 hull steel plate surface cracks refer to the linear cracks on the surface of RINA EH36 hull steel plate, which should generally be the same as the forging or rolling direction. Formation reason: it is mainly due to the hairline, hot crack and cold crack caused by surface over burning, decarburization, looseness, deformation and excessive internal stress during processing (forging, rolling, heat treatment, quenching and tempering), as well as the high content of sulfur and phosphorus impurities on the surface. Inspection method: RINA EH36 hull steel plate surface cracks can be detected by naked eye observation, acid pickling, magnetic particle inspection, coloring inspection and metallographic method.
