Every customer who has visit us and witness the steel materials before delievry will be impressed by our quality control departemnt. Even not come to inspect the steel materials before delievry, our quality control departemnt will also send inspection report to the customer. For each order, no matter its quantity and value, our quality control departemnt will make strict inspection before delivery, the inspection contents include apperance, tolerance, dimension, mark, special requirements of customers, etc. To guarantee our steel materials sent to the customer is qualified.
EN10025-2 S235J2 steel is equivalent to our Chinese teel grade Q235D. They are both done low temperature impact test at -20℃. Sometimes S235J2 would be used to built containers which can bear low temperature sea water. LR grade D seafaring ship steel, S235J2+N steel plate, following a rolling process within a certain temperature range, producing a material in a condition equivalent to that obtained after normalization. With the result that the specified mechanical properties values are conserved even after normalization treatment.
Mechanical Properties A242 steel:ASTM A242 specification is made for low alloy steel with high strength, it has good atmospheric corrosion resistance, some applications has shown that it has better corrosion resistance than ASTM A36 steel and ASTM A572 Grade 50.Tensile: 70 ksi min (3/4 and under), 67 ksi min (3/4-1.5) 63 ksi min (over 1.5-4)Yield: 50 ksi min (3/4 and under), 46 ksi min (3/4-1.5) 42 ksi min (over 1.5-4)Elongation: 16% min in 8” 19% min in 2” (for plates wider than 24”)
304 stainless steel plate products have strong corrosion resistance. For ordinary alkali solution and organic acid, inorganic acid has good corrosion resistance. This material LR grade D seafaring ship steel is a high alloy steel, which can resist corrosion in air or chemical corrosive medium.
Relying on the background of high-quality steel resources and its own strong steel machining capabilities, BBN comany can not only supply various steel material products, such as steel coils, steel plates, LR grade D seafaring ship steel sheet, steel pipes, and shaped steels, but also provide a variety of steel deep processing services like cutting, welding and grinding. Through continuous technological innovation and after-sales service optimization, the company has its own world on the domestic and international steel industry stage!
The boiler steel plates are among our main products. Other than standard size boiler steel plates, we also provide LR grade D seafaring ship steel cutting, bending and so on processing to change plate size and shape according to your requirements.
