Stainless Steel 304/304L/304H Round Bars

Vision Alloys (India) is an exceedingly manufacturer, exporter, stockiest and supplier of Stainless Steel 304 Round Bars and SS 304/304L/304H Round Bars and Rods that are being sourced by using dominating nature of rough material.

With respect to a couple of stainless steel audits, these Stainless Steel 304 Round Bars and Rods is the common 18/8 in the gathering of stainless. The specification includes fantastic welding performance and impartial austenitic structure, these stainless steel 304 Rods is for the most part used as a part of transportation and modern machines.

Stainless Steel 304L Round Bars and Rods has a significant measure of the similar mechanical characteristics of SS 304, however this particular audit is extra low-carbon dissimilarity. It is also known as S30403, these Stainless Steel 304L Round Bars has most outrageous measure of carbon substance that disposes of the carbide precipitation that comes in the midst of the welding system. For the reason of these qualities, these Stainless Steel 304L Rods can be used as a piece of welded state, even in enormously ruinous structures.

These Stainless Steel 304H Round Bars and Rods offers updated raised temperature quality when uncovered to temperatures for more than 800 degrees Fahrenheit. These Stainless Steel 304H Round Bars too has better whole deal and transient slither control than Alloy 304L at temperatures for more than 500 Deg C and is more trying to honing than Alloy 304L. Generally called UNS S30409, these SS 304H Rods is again and again used as a substance of advancement for up to around 1500 degrees Fahrenheit.
