In metallurgy, stainless steel, also known as inox steel or inox from French "inoxydable", is a steel alloy with a minimum of 10.5% chromium content by mass.

Stainless steel does not readily corrode, rust or stain with water as ordinary steel does. However, it is not fully stain-proof in low-oxygen, high-salinity, or poor air-circulation environments. There are different grades and surface finishes of stainless steel to suit the environment the alloy must endure. Stainless steel is used where both the properties of steel and corrosion resistance are required.

Stainless steel differs from carbon steel by the amount of chromium present. Unprotected carbon steel rusts readily when exposed to air and moisture. This iron oxide film (the rust) is active and accelerates corrosion by forming more iron oxide; and, because of the greater volume of the iron oxide, this tends to flake and fall away. Stainless steels contain sufficient chromium to form a passive film of chromium oxide, which prevents further surface corrosion by blocking oxygen diffusion to the steel surface and blocks corrosion from spreading into the metal's internal structure, and, due to the similar size of the steel and oxide ions, they bond very strongly and remain attached to the surface.

Passivation occurs only if the proportion of chromium is high enough and oxygen is present.

We have emerged as a leading organization, engaged in offering superior quality Stainless Steel 316Ti (1.4571) Pipes. These pipes are manufactured by our skilled professionals using excellent quality steel and the latest technology. Offered pipes are essentially a standard carbon 316 type with titanium stabilization and is similar in principle to the titanium stabilization of the 304 (1.4301) type to produce 321 (1.4541).  In order to ensure quality, the entire range is stringently tested on various parameters by our quality controllers. Apart from this, clients can avail the entire range from us in various customized options and at industrial leading prices.


  • Rugged construction
  • Durable
  • Rust resistance

Mechanical Properties:

  • The presence of titanium to 1.4571 does, however, give some improvements to mechanical strength, especially, at elevated temperatures above about 600 C. and care must therefore be exercised in selecting 1.4404 as a substitute under these conditions
  • The 1.4571 may however have inferior impact properties at ambient temperatures, compared to the 1.4404 / 1.4432 types


  • The machinability of 1.4571 can also be an issue as the titanium carbo-nitrides particles can result in higher tool wear and may not cold form or cold head as readily as the 1.4404 / 1.4432 types

Corrosion Resistance:

  • There is also some evidence that the 1.4571 type may have inferior pitting and stress corrosion cracking resistance, compared to the 1.4404 / 1.4432 types, although the general corrosion resistance can be assumed to be generally similar
  • The titanium stabilised 1.4571 grade may also be prone to 'knife line attack' in the heat-affected zones of welds, very close to the fusion zone where the carbo-nitrides have redissolved in the solid steel matrix


  • The weldability of the 1.4571 and 1.4404 / 1.4432 can be assumed to be similar. Neither of the grades can be expected to weld 'easier' or 'better' than-the-other
  • Niobium stabilised fillers (welding consumables) should be used for welding the 1.4571, especially where elevated temperature weld strength may be important
  • In other circumstances a '316L' filler should give a matching weld metal aqueous corrosion resistance to that of the 'parent' 1.4571 '316Ti' material

Austenitic Manganese Steels

Metallurgical Affect of Manganese on Steels Manganese is present in all steels as a de-oxidizer. Manganese reduces the tendency towards hot-shortness or popularly known as red-shortness resulting from the presence of sulphur, which enables the metal to be hot-worked. When manganese is absent or very low, the predominant sulphide in iron sulphide (FeS), which forms the eutectic with iron, has affinity to form thin continuous films around the primary crystals during solidification of the steel. Manganese improves the strength properties of steel, while marginally impairing its elasticity. In addition, manganese has favourable influence on forging, welding and grain refining properties in steel castings. A higher content of manganese in the presence of carbon substantially increases the wear resistance. With up to 3% of manganese, the tensile strength of steels increases by about 10 kg/mm2 for every added percentage of manganese. With addition of manganese in contents above 3% to 8%, the increase rises more slowly and at content more than 8% of manganese, it drops off again. The yield point behaves in a similar manner. Manganese enhances the depth of hardening of steels.
