DNV Approval Certificated Corten A bar yield strength

In order to further transform the operation mechanism, establish the operation concept of "market-oriented, customer-centric", strive to improve our core competitiveness and promote the rapid development of business; further strengthen customer marketing management, subdivide customer groups, establish a top-down, crisscross, hierarchical marketing mechanism of "everyone is a marketer", and provide for the needs of different levels of customers Corresponding services.

Corten A bar yield strength, Wear-resistant steel plate has good heat resistance:
The alloy wear-resistant layer is recommended to be used under ≤600℃. If vanadium, molybdenum and other alloys are added to the alloy wear-resistant layer, it can withstand high temperature wear of ≤800℃. The recommended operating temperature is as follows: Ordinary carbon steel base plate is recommended to be used in working conditions not higher than 380℃; Low-alloy heat-resistant steel plates (15CrMo, 12Cr1MOV, etc.) substrates are recommended to be used in working conditions not higher than 540℃; The heat-resistant stainless steel substrate is recommended to be used at no higher than 800℃.

The trend of international shipping development of large-scale ships and strategic joint ventures puts forward higher requirements for modern ports. Modern ports no longer use the general cargo throughput as a measure sign, and container throughput will become the main sign to measure the role and status of modern ports. The average container capacity in 2000 is 3200teu, and it is expected to be 5500teu in 2020.

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