The shipbuilding and offshore platform steel plates are our main products. The shipbuilding and offshore platform steel plates are produced according to ASTM A131/A131M technical standard. Our shipbuilding and offshore platform steel plates accept ABS, LR,CCS, RINA, DNV GL, BV, NK, KR, RMRS and so on classification societies’ inspection and will obtain EN10204 3.2 MTC. The typical shipbuilding comparison of S355K2 steel and A573 Grade 70 steel and offshore platform steel grades are grade A/B/D/E, AH32, DH32, EH32, FH32, AH36, DH36, EH36, FH36, AH40, DH40, EH40, FH40, etc.

comparison of S355K2 steel and A573 Grade 70 steel, Wear-resistant steel plates are easy to overheat, so pay attention to heating temperature and holding time. It is recommended to heat up to 820 degrees for proper insulation. Tempering temperature: 320 degrees, sufficient time. Hardness: 45-48HRC. Good performance. Salt bath NaCl:BaCl=3:7 can be heated at a temperature of 820, time is 30 seconds/mm (mm refers to the effective thickness of the part), oil cooling. Tempering temperature is 280, air furnace time is 2 hours, and nitrate furnace time is 30 minutes.

The advantage of plasma cutting is that it can cut thin plates, stainless steel and non-ferrous metals, and the cutting speed is fast. The disadvantage of plasma cutting is that the incision will have a slope, and there will be noise when cutting. The advantages of water jet cutting are wide cutting range and environmental protection, but the disadvantages of water jet cutting are slow cutting speed and high energy consumption. Do you know what is the best cutting method for comparison of S355K2 steel and A573 Grade 70 steel?

Our company will accept the product quality objection registration record, pass it to the comparison of S355K2 steel and A573 Grade 70 steel production unit and relevant departments, and timely coordinate the supervision of product comparison of S355K2 steel and A573 Grade 70 steel quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
