Stainless Steel Hex Bar

Most commonly alloy grades like 304 and grade 316 are used to produce ss hexagonal bars. This is because these two austenitic ss grades offer multiple properties which prove to be fruitful to our clients. For instance, ss 304 hex bar has good resistance to corrosion, exhibits good mechanical strength and is a low conductor of heat and electricity.

Hence this alloy is useful for applications where 17mm stainless hex bar is required to reduce the cost of the entire operation. Since alloy grade 304 is considered to be an economical and popular alloy choice amongst several industries. But in times when the properties of grade 304 prove to be less, our clients have an option of choosing grade 316 stainless hex bar, which is also known as marine grade SS. The mechanical properties such as tensile strength, hardness as well as corrosion resistance properties of grade 316 tend to be much higher as opposed to grade 304.

Hex bars or as fully known as hexagonal bars find use in architecture, power generation, petrochemicals, offshore or onsite drilling etc. The weight of ss hexagonal bar is required to be in consultation with the application it is to be used for. Apart from the weight the application it is to be used for must also take into account the ss 316 hex bar sizes. As one of the leading exporter and ss hex bar manufacturer in India, we offer reasonable prices and assist all our clients with their requirements.

303 stainless steel hex bar vs 304 Hexagonal bars

Belonging to the austenitic stainless steel category of alloys, both grade 303 as well as grade 304 have a similar chemical make up. Albeit there are differences known in their characteristics.  Considered to be a modification of the more conventionally used 18/8 alloy grade, stainless steel 303 has a significant addition of sulfur in its alloy. While adding sulfur to austenitic grades such as alloy 303 tends to improve its machinability, this particular alloy notes a decrease in certain properties. For instance, properties such as weldability and resistance to corrosion are notably reduced. While grade 303 is able to withstand mildly corrosive environments, its resistance to corrosion pales to that of the widely used stainless steel grade 304.

Intended to ease the machinability problems encountered by grade 304, the addition of sulfur in alloy 303 is what assists in breaking up turnings. This, in turn, reduces drag on the cutting tool, by producing small brittle chips. Hence, grade 303 could be machined at high speeds along with deep cuts and heavy feeds. Unlike stainless steel grade 303, grade 304 is a very popular alloy making it invaluable across multiple sectors. This is not only due to the economical price of grade 304, but also its corrosion resistance properties, which are much higher than grade 303.
