A specification that caters to various shaped bars produced in ss grade, according to SS Rod Suppliers is the ASTM A276. Moreover, different grades such as alloy 304 or grade 316 can be used in the production of SS Round Bar in accordance with the ASTM A276 specification. Since austenitic alloy grades are highly ductile, forming various shapes including the SS Hex Bar can be done with much ease. Both hot forming and cold forming methods could be used in the manufacture of the ASTM A276 Round Bar.
Cold forming the SS Flat Bar can prove to be particularly advantageous because it offers a cost saving alternative because of its reduced cost. Aside from exhibiting higher tensile strength properties, the surface of the Forged SS Round Bar processed by cold forming has a high quality finish and close repetitive tolerances. On the other hand, SS Round Bars Manufacturers India using hot forming process note the following advantages i.e. higher surface profile tolerance, superior accuracy, reduced metal spring back effect as well as ease in plastic deformation of complex shapes. Regularly, the Polished SS Round Bar is used as a sanitary bar due to the Hygenic and non-toxic properties associated with polished SS alloys. And a SS Bright Bar which is also a surface treated alloy could be used along with polished stainless steel components in the food and beverage industry.

Being one of the most versatile alloy grades around, stainless steels offer a ton of advantageous properties, which could be useful in pump shafts. Selecting an appropriate material can not only reduce the cost of the operation, but it also could work out as an investment. While stainless steels are much cheaper in comparison to Inconel or Hastelloy, an advantage of these bars is that their resistance to corrosion is high as is their mechanical strength. But what makes stainless steel unique is that the chemistry could be modified to suit their creep strength as well as welding requirements by controlling the content of carbon in the alloy of several stainless steel grades.
Moreover, in pump shafts, the stainless steel bars used undergo different levels of not only static and dynamic stresses of a mechanical and thermal nature but also external stresses such as abrasion, erosion, corrosion and cavitation. Pump shafts also note the occurrence of vibrations during their application, which in turn is another kind of stress. Also, not to discount the corrosion resistance properties required by them along with the chances of the alloy getting deformed due to the fluctuation of temperature. Since stainless steel grades can exhibit superior corrosion resistance properties along with being able to withstand a wide range of temperatures including cryogenic and elevated settings, stainless steel round bars are well suited to be used for pump shafts.
