Stainless steel is an alloy of iron that is resistant to rusting and corrosion. It contains at least 11% chromium and may contain elements such as carbon, other nonmetals and metals to obtain other desired properties. Stainless steel’s resistance to corrosion results from the chromium, which forms a passive film that can protect the material and self-heal in the presence of oxygen
Completely and infinitely recyclable, stainless steel is the ¡°green material¡± par excellence. In fact, within the construction sector, its actual recovery rate is close to 100%.
Stainless steel is also environmentally neutral and inert, and its longevity ensures it meets the needs of sustainable construction. Furthermore, it does not leach compounds that could modify its composition when in contact with elements like water.
Stainless steel must contain at least 10.5 percent chromium. Depending on the grade, it may contain much higher chromium levels, and additional alloying ingredients like molybdenum, nickel, titanium, aluminum, copper, nitrogen, phosphorous or selenium.
In addition to these environmental benefits, stainless steel is also aesthetically appealing, extremely hygienic, easy to maintain, highly durable and offers a wide variety of aspects. As a result, stainless steel can be found in many everyday objects. It also plays a prominent role in an array of industries, including energy, transportation, building, research, medicine, food and logistics.

Grade 304L is widely used in the manufacturing industry and all standard welding techniques can be used for 304L plate and 304L pipe. The “L” in 304L stands for “low carbon content” and indicates a maximum carbon content of 0.035%. The “H” in 304H stands for “High Carbon Content”, which means that the carbon content is not less than 0.04% and not more than 0.10%.

The flange is second most used joining method after selding. Flanges are used when joints need dismantling. It provides flexibility for maintenance. Flange connects the pipe with various equipment and valves. Breakup flanges are added in the pipeline system if regular maintenance in required during plant operation.
A flanged joint is composed of three separate and independent although interrdlated components; the flanges, the gaskets, and the bolting; which are assembled by yet another influence, the fitter. Special controls are required in the selection and application of all there elements to attain a joint, which has acceptable leak tightness.
A flange is a protruded ridge, lip or rim, either external or internal, that serves to increase strength (as the flange of an iron beam such as an I-beam or a T-beam); for easy attachment/transfer of contact force with another object (as the flange on the end of a pipe, steam cylinder, etc., or on the lens mount of a camera); or for stabilizing and guiding the movements of a machine or its parts (as the inside flange of a rail car or tram wheel, which keep the wheels from running off the rails). The term “flange” is also used for a kind of tool used to form flanges.

17-4 PH stainless steel is a martensitic precipitation hardening stainless steel with high strength and hardness, corrosion resistance and excellent mechanical properties. It is the most widely used of all precipitation hardening stainless steels.

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
