ASTM A312 TP304 Stainless Steel Thick Wall For General Corrosive Service
TONG CHUANG special steel has been engaged in seamless welded steel pipes of austenitic stainless steel and nickel alloy steel (Hastelloy, Monel alloy, Inconel alloy and Inconel alloy) for more than 25 years, and sells steel pipes every year. More than 80000 tons. Our customers cover more than 45 countries, such as Italy, Britain, Germany, the United States, Canada, Chile, Colombia, Saudi Arabia, South Korea, Poland, Singapore, Australia, France, etc.
A312 Tp304 tube is pushed or pulled to form a shape usually formed from a round billet of raw material. It is more corrosion resistant than ordinary 304 stainless steel pipe. Our 304 stainless steel seamless tube has a low carbon content, making it highly weldable and formable. Stainless steel 304 welded pipe can be in different shapes such as SS 304 round pipe or SS 304 square pipe. SS 304 Erw tube is used for long service chemical and industrial applications. Our products are of high quality and have very competitive prices in the market.
说明
304 belongs to American Standard austenitic stainless steel. It is a common material in stainless steel, with a density of 7.93 g / cm. It is also called 18 / 8 stainless steel in the industry. High temperature resistance of 800 ℃, with the characteristics of good processing performance and high toughness, it is widely used in industry, furniture decoration industry and food and medical industry.
Our product range in 1.4301 are tubes and pipes, fittings and flanges, accessories.
