There are many types of steel 16mn, mainly divided into two categories, the first is the seamless steel pipe, the second is the pipe joints. Both Although only one word, but the nature and purpose but not as big caliber big 16mn thick-walled steel, we live in the most common is 16mn seamless. 16Mn straight seam steel pipe due to low carbon content, hardened tendency to decrease, cold cracking tends to decrease. But with the intensity level increases, the thickness increase, still has a certain tendency to cold cracking. Because when welding is often used in the field of cellulose electrodes, self-shielded flux-cored wire and other high hydrogen content of welding consumables, small 16mn thick-walled pipe line energy prices, the cooling speed, will increase the sensitivity to cold cracking 16mn thick-walled steel pipe manufacturers need to take the necessary measures welding, such as welding before preheating. Standard: general structure seamless steel pipe: (GB / T8162-1999) transmission fluid with seamless steel pipe: (GB / T8163-1999) low-pressure boiler seamless steel pipe: (GB / T3087-1999) high-pressure boiler Seamless Steel Tube: (GB / T5310-1995) fertilizer seamless steel pipe: (GB / T6479-2000) petroleum cracking seamless steel pipe: (GB / T9948-1988) ship tube: (GB / T5312-1998), etc. and so now I have a lot alloy pipe, pressure pipe stock 16mn thick-walled steel pipe, will discount the price, wholesale and retail ways, to provide you with fast quality service, welcome new and old customers to negotiate, Power Conference.
