The heat treatment hardness of DC53 mold steel is higher than that of SKD11, astm a573 structural steel grade 70 properties, the high temperature is 520-530 ℃, and the high hardness can reach 62-63HRC after tempering. In terms of strength and wear resistance, mold steel DC53 exceeds SKD11 mold steel. The toughness is twice that of SKD11 die steel. The toughness of DC53 is more prominent in cold work die steel. Tools made with DC53 rarely crack and crack, greatly increasing the service life.
As the boiler steel plate astm a573 structural steel grade 70 properties is working under medium temperature (below 350 ℃) and high pressure, the boiler steel plate is not only subjected to high pressure, but also subjected to impact, fatigue load and water and gas corrosion. The performance requirements for boiler steel mainly include good welding and cold bending performance, certain high temperature strength, alkali corrosion resistance, oxidation resistance, etc.
We have built solid cooperation with Myanmar Navy since 2015, starting from a try order about 412 tons LR AH36 shipbuilding steel plates. Myanmar navy builds frigate every year and book shipbuilding steel materials from us regularly. This time, the Myanmar navy’s local representative visit us and put another order about 2025 tons LR grade A steel plates. According to clients requirements, we arranged astm a573 structural steel grade 70 properties SGS inspection for the LR grade A steel plates before shipping and send them inspection report.
