 
                           SS 347/347H Round Bars/Rods is available on many distributors and manufacturers but if you want to buy from best dealer and you never want to face any security and quality issue about the product then champak steel & Engg. is here for you. Champak Steel & Engg. Co offers a wide range of SS 347/347H Round Bars/Rods. The quality is the reason behind the popularity of our industry.
It is an SS grade that offers excellent resistance for irregular corrosion. These rods are used to assemble the hardware. There is some standard specification of stainless steel, the first one is its length, and it should not be greater than 8m. But it also depends on the client's requirements. The sizes of the bright bar and round bar also a matter. The tolerance of the material again depends on the clients as per their requirements. Steel can be rolled, peeled, or cold drawn according to the condition.
According to nature, stainless steel can be magnetic and non-magnetic. Physical property remains the same in every type of steel it contains thermal expansion, density, thermal conductivity, specific heat and modulus of elasticity. The mechanical property contains its hardness, elongation, tensile strength, and its grade.
It is used in application in the following industries; food processing- for storage and its equipment, chemical processing, polythionic acid service, waste heat recovery, pharmaceutical production, fluid catalytic, petroleum refining. It is also used as some typical applications are high-temperature steam services, high-pressure pipes, heavy-duty systems, heat exchanger tubes, radiant super heater, etc.
The following types of bars are now in use; round bars, hexagonal bars, polish bars, rods, round rods, flat bars, etc. the advantage are a good formality, high strength, mechanical stresses for high resistance.
The material test is conducted to assure the quality of the product. Tests that perform such as hardness test, pitting resistance tests, flaring tests, general corrosion tests, macro, and micro tests, mechanical test, flattening test and many more tests are performed on the material.
The packaging can be done in the following manners like it may be a wrap, hexagonal packaging, wooden boxes packaging, crates packaging, bundles of the material and some time depends on the client's requirements.
