ASME B36.19M is the standard specification for stainless steel pipes, which specifies the dimensions, tolerance, and manufacturing requirements for both welded and seamless pipes.

Though 310 is ideal for high temperature use, it should not be exposed to the severe thermal shock of repeated liquid quenching or where aqueous corrosive contaminants are present.

Steel bars are one of the core components of any manufacturing
industry or for that matter any industry that relies on machineries.
Thanks to its versatile applications, steel bars find itself in the
epicenter of most of engineering industries, be it automotive, textile,
fabrication, construction, cement, ship building, paper and pulp,
defence, heavy earth moving equipments or aerospace.
The overwhelming popularity of steel bars is owed to the fact that
it is possible to be produced in varying types, shapes, sizes, and
grades of bars to cater the exact technical requirements. Steel
bars generally have the shapes such as flat, round, hexagonal,
square and channel and on most of the occasions, it is the shape
of the bar that defines its application area

Stainless steel nuts and bolts are often chosen for their corrosion resistance in corrosive environments. The problem, however, is that standard stainless steel nuts and bolts cannot provide the high strength that carbon steel can provide, which leads to the risk of fastener failure.

316 Stainless Steel Characteristics
Type 316 stainless steel tubing is similar to 304, but with the addition of molybdenum, which improves the alloys corrosion resistance. The austenitic structure allows excellent toughness, even down to extremely low temperatures. These grades have excellent weldability, with or without the addition of filler metal. 316 / 316L stainless tube is available as round, square or rectangular shapes. It is available as welded and seamless. It contains additional molybdenum and nickel than 304 stainless, which increases corrosion resistance of the metal. Decreased weldability is exhibited in 316L alloys due to increased carbon in the alloy. It is used for tube in more aggressive environments than 304 tube.

SAE 304 stainless steel is the most common stainless steel. The steel contains both chromium (between 18% and 20%) and nickel (between 8% and 10.5%)[1] metals as the main non-iron constituents. It is an austenitic stainless steel. It is less electrically and thermally conductive than carbon steel. It is magnetic, but less magnetic than steel. It has a higher corrosion resistance than regular steel and is widely used because of the ease in which it is formed into various shapes.[1]

stainless steel flange uses the flange as the interface between two sections of the pipe connection, rather than directly connecting the pipe. Its advantage is that compared with the straight pipe connection, the stainless steel flange is safer and more reliable, and the interface is more secure.

All steels have the same basic iron and carbon composition, but stainless steel also contains a healthy dose of chromium¡ªthe alloy that gives stainless steel its famous corrosion resistance. There are multiple grades called stainless steel, each with slightly different alloy composition, and therefore slightly different physical characteristics.

Steel flanges provide an easy access for cleaning, inspection or modification. They usually come in round shapes but they can also come in square and rectangular forms. The flanges are joined to each other by bolting and joined to the piping system by welding or threading and are designed to the specific pressure ratings; 150lb, 300lb, 400lb, 600lb, 900lb, 1500lb and 2500lb.

A flange can be a plate for covering or closing the end of a pipe. This is called a blind flange. Thus, flanges are considered to be internal components which are used to support mechanical parts.

Stainless steel 316 butt weld joints are made of chrome-nickel-molybdenum alloy austenitic stainless steel. The material has good corrosion resistance, similar strength to 304 grade steel, and good hardness.
