Stainless Steel basically is an alloy of Iron with a minimum 10.5% of Chromium in it. The Chromium produces a thin layer of oxide on the surface of the steel known as the ‘passive steel’ and hence the “Stainless” appearance. Increasing the amount of Chromium increases the resistance against the corrosion of the steel. Along with Chromium, Stainless Steel also contains varying amounts of Carbon, Silicon and Manganese. Other elements such as Nickel and Molybdenum may be added to impart other useful properties such as enhanced sturdiness and increased corrosion resistance. As an element, Stainless steel is 100% recyclable, corrosion-resistant, conserving-free, tenacious and hygienic.

The stainless steel family tree has several branches which may be differentiated in a variety of ways e.g. in terms of their areas of application, by the alloying elements used in their production or perhaps the most accurate way, by the metallurgical phases present in their microscopic structures –

  • Ferritic
  • Martensitic (including precipitation hardening steels)
  • Austenitic
  • Duplex steels, consisting of mixture of ferrite and austenite.

Austenitic : Austenitic steels have extended as their primary phase (face centered cubic crystal). These are alloys containing chromium and nickel (sometimes manganese and nitrogen), structured around the Type 302 composition of iron, 18% chromium, and 8% nickel. Austenitic steels are not hardenable by heat treatment. The most familiar stainless steel is probably Type 304, sometimes called T304 or simply 304. Type 304 surgical stainless steel is an austenitic steel containing 18-20% chromium and 8-10% nickel.

• Good to excellent corrosion resistance
• Good weldability and formability
• Good creep resistance
• Non-magnetic

Austenitic types have good to excellent type of corrosion resistance, and has exceptional molding ability and durability.

Ferritic : Ferritic steels have ferrite (body centered cubic crystal) as their main phase. These steels contain iron and chromium, based on the Type 430 composition of 17% chromium. Ferritic steel is less ductile than austenitic steel and is not hardenable by heat treatment. Molybdenum may be combined to some grades to improve corrosion resistance. These type of steels are magnetic because of their ferritic structure.

• Low Carbon and Nickel content
• Good Weldability and Toughness
• Magnetic

Martensitic : The characteristic orthorhombic martensite microstructure was first observed by German microscopist Adolf Martens around 1890. Martensitic steels are low carbon steels built around the Type 410 composition of iron, 12% chromium, and 0.12% carbon. They may be tempered and hardened. Martensite gives steel great hardness, but it also reduces its toughness and makes it brittle, so few steels are fully hardened. These grades contain no, or small, amounts of nickel, and molybdenum is seldom added. Adding some nickel and reducing the carbon content improves the poor weldability of martensitic grades.

• High Strength
• Formidable Wear-Resistance
• Low Corrosion Resistance.

Duplex Steels are a combination of Ferritic as well as Austenitic elements, and merges the properties of both the components so as to create a hybrid type of steel. Duplex Steels are mainly characterized by the high Chromium content (20.1 -25.4%) and low Nickel content (1.4 – 7%). Due to the low Nickel content, it makes the Duplex Steel price secure. Molybdenum (0.3 – 4%) and Nitrogen are added to increase corrosion resistance.

• High Strength and Toughness
• Very good corrosion resistant
• Light-weight
• Good Weldability

Applications of  Stainless Steel Fasteners includes

1. Stainless Steel Fasteners Suppliers , needless to say, are mainly used for Stainless Steel sheets to ensure proper and permanent installation.

2. Fasteners made from precipitation hardened grade stainless including A286 Stainless are particularly useful in applications such as outdoor equipment, medical devices and chemical and food processing equipment or anywhere corrosive element exposure is possible.
3. These kind of fasteners are also commonly used for Commercial aspects, Home Appliances, Vehicle parts, and also for aluminium or steel made furniture.

4. Stainless Steel Fasteners are used in surgical instruments and also Industrial equipment as the resistance to corrosion is a major advantage.

5. They are also used as an aerospace structural alloy and also as a component for the construction of large buildings.

We have a state of the art mill facilities, access which runs at a full capacity due to export order overload. We have 3 heavy punch machines for shaping the bar. We also have threads machines to make NPT, BSPT & BSPP threads to the forgoing. Added to that we have in house testing facilities like Spectro machine, PMI Machine, MechanicalTestt, Hardness Test, Ultrasonic Testing, Hydrostatic Testing, Pressure testing and manual inspection of gauge.

The production process can be divided separately for different type of fasteners:

Nuts : Nuts are manufactured from hex bars. The hex bars are subject to CNC Machining that ensures the nuts are compatible with the bolts of the given size.

Bolts : The bolts are manufactured from round bars either original bright or forged. The bolts are then threaded as per size. The head is either round, hex or of different shape as required in order specification.

Washers : Washers are manufactured from plates. The size of hold depends on the bolt and nut along with which it has to be used.
Our intelligent procurement module places a lot of emphasis on selection of raw material. As much as possible, we try to procure Japanese and European origin raw material domestically or from the international markets. Secondary preference is given to Indian and Chinese origin raw material.

Fasteners manufacturer Om Tubes is backed by all world class certifications including ISO 9001:2008, ISO 14001:2004, OHSAS 18001:2007 & CE-PED 97/23/EC.

This heat number is 100% traceable to our records and we maintain very strict watch to ensure the authenticity of our brand isn’t duplicated by other brands.

The Processing of steel carp and alloy together leads to the production of Stainless Steel. The amount of Alloy mixed decides the capability of the Steel works.

But still they are following steps:

1. Step one is to melt the metal including alloy and non-alloy into an electric arc furnace and later on adding the chemical energy like carbon, ferrosilicon, oxygen or fuel gas mixtures to speed up the process

2. After the melting process is done. The melts still is further processed in AOD which is Argon-Oxygen Decarburization. In which the carbon content is reduced and the mixture of Argon and Oxygen is added.

3. If we need low amount of Argon and oxygen then melted steel is added to the VOD which is Vacuum Oxygen Decarburization. And then melted steel is poured on the ladle
