AMS 5639 is the AMS number of the 304 stainless steel. Similarly, the UNS number for this one would be S30400. The specification and standards are the same as that of the ss 304 products. They are available in customizable dimensions, with the same chemical composition. And thus, they can withstand high temperatures and pressures.
The ASTM A276 304 Stainless Steel has excellent forming as well as excellent welding characteristics. In fact, the 304 SS Hollow Bar can be welded by all standard fusion techniques, both with and without the use of filler metals. Although, heavy welded sections in the Ss 304 Flat Bar may require a post weld annealing treatment for maximum corrosion resistance.
It can be noted that the 304 SS Flat Bar has an excellent performance in a wide range of atmospheric environments as well as many corrosive media. Bars manufactured from grade 304 stainless steel are considered to be resistant to potable water that contains up to about 200 mg/L chlorides at ambient temperatures. the corrosion resistant action of the 304 SS Round Bar reduces to about 150 mg/L at a slightly higher temperature of 60 °C.
The Stainless Steel 304 Round Bar is made up of 304 grade stainless steel material. It has around 18% chromium and 8% nickel in its chemical composition. The Stainless Steel 304 Round Bar shows high resistance to corrosion and enhanced strength properties. The material is quite strong with around 515 Mpa min tensile strength and min yield strength of 205 MPa.The 304ss round bars are capable of withstanding high temperatures and high pressures. These bars are also used in pressure vessels as they are capable of retaining their features in a high pressure environment as well. The ss 304 round bars are available in customizable dimensions.
The 1.4301 AISI 304 Cold Rolled Bars are made with 304 grade stainless steel and are formed by cold rolling. This is one of the most versatile and widely used stainless steel bars that have 18% chromium and 8% nickel in its chemical composition. This is an austenitic grade ss that can be severely deep drawn. The Stainless Steel 304 Round Bar offers high strength, and good resistance to corrosion, which is why they are used in a wide range of applications.
