FAQs
What is super duplex stainless steel?
Super duplex stainless steel refers to a high-performance family of stainless steels with about 25% chromium content. These alloys have a dual-phase microstructure, combining both austenitic and ferritic grains for enhanced strength and corrosion resistance. To learn more, check out our related blog on What Is Super Duplex Stainless Steel Material?
What is the difference between 2205 duplex stainless steel and super duplex stainless steel?
Grade 2205 (UNS S32205) is a widely used standard duplex stainless steel known for its good corrosion resistance and strength. Super duplex stainless steels offer even higher corrosion resistance and mechanical strength. For more details, check out our related blog on Difference Between Duplex and Super Duplex Stainless Steel.
What is a super duplex pipe?
Super duplex pipes combine the benefits of both ferritic and austenitic steels, offering high strength from the ferritic structure and excellent corrosion resistance from the austenitic structure. They are also highly resistant to stress corrosion cracking.

FAQ’s About ASTM A106 Grade B Pipes
What is ASTM A106 Grade B pipe?
ASTM A106/A106M Grade B is a seamless carbon steel pipe specification intended for high-temperature service. The exact project suitability depends on the governing piping code, design conditions and purchase specification.
What is the difference between ASTM A106 Grade B and ASTM A53 Grade B?
ASTM A106 Grade B is a seamless high-temperature-service pipe specification. ASTM A53 Grade B covers welded and seamless pipe for mechanical and pressure applications and ordinary steam, water, gas and air service. Select the specification required by the project and design code.
What sizes does Kalpataru supply?
The current brief lists a Kalpataru supply range of 1/2 to 36 in NPS and Schedule 10 to XXS, subject to size and availability. ASTM A106/A106M itself has a wider standard scope.
What is the maximum temperature of ASTM A106 Grade B pipe?
Do not use one universal maximum temperature from the ASTM material specification. Allowable service depends on the design code, pressure, wall thickness, allowable stress and project conditions.
Is ASTM A106 Grade B seamless or welded?
ASTM A106/A106M is a seamless carbon steel pipe specification. Do not describe ERW, LSAW or other welded pipe as ASTM A106 product construction.
What tests are required for ASTM A106 Grade B pipe?
The specification includes mechanical testing and bend/flattening testing as applicable, together with hydrostatic and/or nondestructive electric testing requirements. The exact inspection package should match the current ASTM edition and purchase order.
What documents can be supplied?
Orders can be supplied with EN 10204 3.1 MTC and, where applicable and agreed, IBR documentation, third-party inspection and project-specific test reports.
How is ASTM A106 Grade B pipe priced?
Price depends on NPS, schedule or wall thickness, length, quantity, origin/mill, testing/certification, coating/end preparation and delivery destination. Send the full requirement for a size-wise quotation.
