Factory Supplier for Stainless Steel in Zambia
Stainless steels generally contain between 10-20%chromium as the main alloying element and are valued for high corrosionresistance. With over 11% chromium, steel is about 200 times moreresistant to corrosion than mild steel. These steels can be divided into three groups based on their crystalline structure: Austenitic: Austenitic steels are non-magnetic and non heat-treatable, andgenerally contain 18% chromium, 8% nickel and less than 0.8% carbon. Austenitic steels form the largest po...

Stainless steels generally contain between 10-20%
chromium as the main alloying element and are valued for high corrosion
resistance. With over 11% chromium, steel is about 200 times more
resistant to corrosion than mild steel. These steels can be divided into
three groups based on their crystalline structure:
Austenitic steels are non-magnetic and non heat-treatable, and
generally contain 18% chromium, 8% nickel and less than 0.8% carbon. Austenitic steels
form the largest portion of the global stainless steel market and are
often used in food processing equipment, kitchen utensils and piping.
Ferritic: Ferritic steels contain trace amounts of nickel, 12-17% chromium, less than 0.1% carbon, along with other alloying elements, such as molybdenum, aluminum or titanium. These magnetic steels cannot be hardened with heat treatment, but can be strengthened by cold working.
Martensitic steels contain 11-17% chromium, less than 0.4% nickel and
up to 1.2% carbon. These magnetic and heat-treatable steels are used in
knives, cutting tools, as well as dental and surgical equipment.

Along with the sustained and stable development of China’s economy as well as the accelerated industrialization, China’s demand for oil and natural gas has kept rising rapidly in recent years. In 2013, China’s oil and natural gas consumption reached 498 million tons and 167.6 billion cubic meters respectively, up 4.5% and 14.6 % year-on-year.
Amid the jumping demand for oil and natural gas, China has enhanced the construction of oil and gas pipeline networks. In 2013, Chinese oil and gas pipeline network pattern initially formed with the total mileage of 106,200 kilometers. In accordance with “Twelfth Five-Year Plan”, the total length will be about 150,000 km by 2015, which will boost the development of oil and gas transmission steel pipes and other related materials to a certain extent.
Welded pipes and seamless steel pipes, especailly SSAW (Spirally Submerged Arc Welding) and LSAW (Longitudinally Submerged Arc Welding), are required in the construction of oil and gas transmission pipeline networks. As of the end of 2013, China had been building and proposed to set up six trunk oil and gas transmission pipelines; CNPC and CNOOC had been establishing and planned 10 gas pipelines which will be completed successively in 2014-2016. The above 16 pipelines need about 11.19 million tons of SSAW (70%) and LSAW (30 %).
