Scope of application of JIS G3101A131 AH40 offshore platform steel : SS400 steel plates and other steel products are suitable for general structural buildings, bridges and ships, and the final products are hot rolled products.
A131 AH40 offshore platform steel, Q215A steel belongs to carbon structural steel. Q215A steel does not contain specially added alloy elements. A131 AH40 offshore platform steel, Q215A steel is mainly used in construction and engineering structures. Chemical composition of Q215A steel: C: ≤ 0.15, Si: ≤ 0.30, Mn: ≤ 1.20, P ≤: 0.045, S ≤: 0.050. Q215A steel has low carbon and manganese content. Q215A steel strength is slightly higher than Q195 steel strength. A131 AH40 offshore platform steel, Q215A steel has good plasticity, good toughness, weldability and process performance. Q215A steel is mainly used in plant building, bridge components, tower, derrick and vehicle and ship manufacturing components.
Titanium microalloying is an element of A131 AH40 offshore platform steel strengthening complex with carbon and nitrogen. The addition of micro amount of titanium in the steel can fix almost all nitrogen and part carbon in the steel, so as to eliminate the strain aging phenomenon and improve the aging impact performance of the steel. At the same time, it can refine the grains and change the morphology of the compounds. According to the atomic weight ratio of Ti and N in A131 AH40 offshore platform steel tin formula (Ti = 3.4n), the content of Ti in steel should be controlled between 0.015 and 0.025%. Generally, the amount of ferrotitanium added to each ton of steel is 1kg.
The boiler steel plates are among our main products. Other than standard size boiler steel plates, we also provide A131 AH40 offshore platform steel cutting, bending and so on processing to change plate size and shape according to your requirements. Welcome to consult us about A131 AH40 offshore platform steel ASTM A204 grade B properties, SA 516 gr 70 temperature range, ASTM A285 grade C chemical composition, boiler steel price and so on questions and ask for offer.
The 365 day service system is implemented, and the business, loading and delivery are handled as usual in holidays and festivals. Actively help users solve difficulties. When users encounter difficulties in handling business, they should actively coordinate with the external solution; if they need to solve the problems internally, they should solve them in a timely manner without prevarication and wrangling. In line with the A131 AH40 offshore platform steel principle of "fairness, justice and timeliness", coordinate with relevant departments and deal with all kinds of objections in a timely manner.
