Improving the hardness of the material is a relatively easy task. Typically the DIN 2391-2 Grade St 35 Carbon Steel Seamless Tubes would have to be processed by either carburization or they could undergo nitriding. Both these processes improve the surface hardness of the DIN 2391 ST35 NBK Seamless Tubes in the presence of either carbon or nitrogen rich substrates via heat treatment.
Differences between Hot Rolled and Cold Rolled Seamless Aug 20, 2020 · The accuracy of cold-rolled seamless steel pipe is higher than that of hot-rolled seamless steel pipe, and the price is also higher than that of hot-rolled seamless steel pipe. Seamless steel pipes are divided into hot-rolled (extruded) seamless steel pipes and cold-drawn (rolled) seamless steel pipes due to their different manufacturing processes.
EN 10305-1 Grade E235+n Carbon Steel Seamless Tubes EN 10305-1 E355+sr seamless cold drawn steel tubes supplier. Standard EN 10305 covers steel produced precision tubes. This standard includes delivery conditions for six different parts. Part 1 or as referred to as EN 10305-1 refers to Seamless cold drawn precision tubes. These precision tubes are specifically designated with the letter E
Precision pipe is the carbon, alloy or stainless steel pipe with high precision sizes. Usually it has been made through hot rolling or cold drawn (cold rolling) processes. So precision pipe is a kind of seamless pipe. It is designed with several advantages:Inside and outside surface no oxide coating; It could bear high pressure, no leaking;

Seamless Steel Pipe/Tube (SMLS Pipe/Tube), API 5L, ASTM Seamless steel pipe has better pressure capacity, strength is higher than ERW welded steel pipe. So it is widely applied in high pressure equipment, and thermal, boiler industries. Generally the welding seam of the welded steel pipe is the weak point, the quality affect overall performance. ASTM Standard for seamless steel pipe
