ASTM A554 TP304 1.4301 Stainless Steel Welded Pipe Bright Annealed
Wenzhou Shangle Steel Co., Ltd. (Shangle) founded in 2017,is a comprehensive company integrating industry and trade.As a leading supplier of stainless steel products in Wenzhou, it has a wide range of products in stock that have been rigorously tested and are ready to be shipped.
Description :
This guide covers standard specification for welded stainless steel
tubing for mechanical applications where appearance, mechanical
properties, or corrosion resistance is needed. The tubes shall be
made from flat-rolled steel by an automatic welding process without
the addition of filler metal. Tubes shall be furnished in one of
the following shapes - round, square, rectangular, or special.
Heat analysis shall be performed wherein several grades of steel
shall conform to the required chemical composition for carbon,
manganese, phosphorus, sulfur, silicon, nickel, chromium,
molybdenum, titanium, columbium, and tantalum.
What is 304 stainless steel?
304 stainless steel is a common material in stainless steel with a
density of 7.93 g/cm³, which is also called 18/8 stainless steel in
the industry. High temperature resistant to 800℃, with good
processing performance and high toughness, it is widely used in
industry and furniture decoration industry and food and medical
industry.
304 is a universal stainless steel, which is widely used to make
equipment and parts that require good comprehensive performance
(corrosion resistance and formability). In order to maintain the
inherent corrosion resistance of stainless steel, steel must
contain more than 18% chromium and more than 8% nickel. 304
stainless steel is a grade of stainless steel produced in
accordance with the American ASTM standard.
Advantages:
1. Corrosion resistance: TP304 stainless steel pipe has excellent
corrosion resistance and can resist erosion by various corrosive
media, such as acids, alkalis, salts, etc.
2. High temperature resistance: TP304 stainless steel pipe has good
high temperature resistance and can maintain good performance at
high temperatures, such as when used in boilers, heat exchangers
and other equipment.
3. High strength: TP304 stainless steel pipe has high strength and
hardness and can withstand greater pressure and load.
4. Other properties: TP304 stainless steel pipe has good thermal
conductivity, electromagnetic shielding, etc., and can be used in
various situations where low temperature needs to be maintained or
electromagnetic interference shielded.
