Q: What is the difference between A249 and A269 stainless tubing? 
A: A269 covers both welded and seamless stainless for general applications or that require corrosion resistance and low or high temp usage including 304L, 316L and 321.  A249 is welded only and used for high temp applications (boiler, heat exchanger). 


Q: Can Stainless Steel be heat treated to increase the hardness?  
A: Martensitic Stainless Steel can be hardened by using quenching and tempering. Ferritic and Austenitic Stainless Steels cannot.


Q: Can stainless steel be used at very low and very high temperatures? 
A: Yes. Stainless steel has excellent properties at both extremes of the temperature scale. Stainless steel can be used down to liquid nitrogen temperatures and up to about 1800℉.


Q: What is the weight per m of piece? 
A: Theoretical weight calculation formula of stainless steel pipe for your reference: (O.D. - W.T.) * W.T. * 0.02491 = KG/M O.D: Outside Diameter W.T.: Wall Thickness Q: How do you ensure the delivery time before shipment? A: North-Pipe sets up several our own branches, offices and warehouses near to the ports in Xingang,Tianjin, Qingdao, Dalian, Shanghai and Guangzhou to speedy the delivery time & increase more lucrative profits for the partners
