Q460D material is a low-alloy ultra-high-strength steel with high hardenability. The critical hardening diameter in oil is 60mm (96% martensite). The steel can obtain high strength after quenching and tempering. The toughness, and can be processed into shape; but the cold deformation plasticity and weldability are low.
Heat treatment is a very important process to improve the performance of A573 grade 70 carbon steel plate etc. metal materials. The process of heating, heat preservation and cooling the steel in solid state to obtain the required structure and properties.
We had a wonderful trip in Phuket Island, Thailand. At the end of 2019, in order to thank employees for their hard work for a year and enrich their lives, our company organized a pleasant trip to Phuket Island, Thailand. The tour lasted 6 days and 5 nights, and returned by plane on the evening of December 27. We took off in Zhengzhou at about 5 o'clock in the afternoon on the 22th December.
Now many manufacturers will use CNC equipment to complete the steel plate cutting processing, this processing method is also gradually increasing, but if you want to make the processing effect meet the specifications and standards, the control requirements of operation technology are also relatively high. Now there are many kinds of steel plate cutting, during the actual processing, it is necessary to select the appropriate processing method according to the cutting requirements of steel plate, so as to achieve the ideal processing effect for A573 grade 70 carbon steel plate.
