ASTM A276 Grade 309 Rod and 309 SS Hex Bar Supplier in India
Usually, austenitic stainless steel bars are either hot finished or they could be cold finished. Yet, some specifications like the ASTM A276 and the ASTM A479 require the produced Stainless Steel 309 Round Bar to meet the mechanical property requirements of the alloy. The mechanical properties which are taken into account normally include the materials tensile strength, yield strength, rate of elongation, and hardness.
Stainless Steel 309 Round Bar
ASTM A276 Grade 309 Rod
Grade 309 is a stainless steel alloy that performs well at elevated temperatures. The ASME SA479 309 Stainless Steel Bar has oxidation corrosion resistance up to a temperature of 1900°F, under non-cyclic circumstances. Though as a cautionary note, manufacturers do not recommend using this alloy at repeated thermal cycling conditions, because at a temperature of 1850°F there is a reduction in the oxidation resistance properties of the aisi 309 stainless steel hex Bar.
The higher contents of both chromium as well as nickel, in grade 309 stainless steel round bar offer properties that rival alloy 304. In fact properties such as corrosion resistance and the resistance to oxidation of the alloy are much superior as compared to grade 304. Moreover, the astm a276 grade 309 Rod retains a larger portion of its strength at ambient temperature as compared to the traditionally used austenitic stainless steel Alloy 304. Because of its chemical makeup, stainless steel 309 stainless steel flat bar can be employed in sulfur containing atmospheres, even if the temperature reaches a point of 1832°F. If the material is to be applied in slightly nitriding, oxidizing, cementing, or in thermal cycling applications, the maximum service temperature for the 309 SS Bar has to be reduced.
