Duplex stainless steel order from Indonesia part1

In mid-April,a new customer from Indonesia came to me and asked me to quote for his order of duplex stainless steel, which included steel pipes, pipe fittings and flanges. How did the client find me? Because when he searched online related keywords such as duplex stainless steel and engineering, customers found that our company not only has rich supply experience, but also can provide customers with meticulous technical services and dedicated after-sales work. We have certificate of ABS 3.2, both for marine and industry, the end user requested company with ABS 3.2 certificate, that is also the reason why client finally choose us.

1.Start quoting

In the initial quotation, the material indicated by the customer is S31803 (pipe fittings, steel pipe) and A182 F51 (flange,branch pipe platform,etc.). Our company also made the first quotation according to relevant requirements. As the quotation was timely, the customer immediately gave feedback: the customer required that the Cr content of S31803 should not be less than 22.5%. After receiving the customer’s feedback, I immediately contacted the company’s technical personnel to ask whether they could meet the customer’s requirements. The technical personnel replied that the customer might need S32205. Here is a brief introduction of 2205 duplex stainless steel.

2205 duplex stainless steel (UNSS31803/S32205) combines many advantages of austenitic and ferritic steels. High content of chromium, nitrogen, molybdenum, this kind of steel has good corrosion properties. Dual – phase structure is helpful to obtain high strength and stress corrosion rupture resistance. Duplex stainless steel also has good weldability.

– Excellent corrosion resistance, high stress corrosion cracking and corrosion fatigue resistance;

– High mechanical strength, good wear resistance and fatigue resistance;

– Low thermal expansion;

So, what’s the difference between S31803 and S32205? In the next article, I will explain the details and introduce more information about this order.
