We excel at executing both small size and bulk orders. We try to incorporate more and more sizes (including the non-standard ones, too) in our stock each year. We also emphasize excellent after sales services. With a rejection rate of less than a percent, we happily claim to be the best choice of consumers.
Know more about the alloy
Grade 321 is established by adding Titanium to stabilize the alloy. It is the right choice for applications up to a temperature of 900 degree Celsius. It exhibits an excellent combination of properties like high strength, resistance to scaling and phase stability with resistance to aqueous corrosion.

This alloy exhibits properties that prove to be extremely beneficial for many industries. It is considerably corrosion resistant. It is resistant to crevices formation in chloride environments up to a temperature of 60 degree Celsius. Grade 321H is the higher carbon variant of this alloy, which has higher strength at higher temperature. This grade of steel has a good thermal resistance, functioning the best at a temperature range of 425-900 degree Celsius. 321H is more suitable for high temperature structural applications as it has higher hot strength. They have excellent weldability with all standard fusion methods, with or without filler metals.
It has as many applications as the beneficial properties. Some of them include its use in manufacturing aircraft exhaust manifolds. They are also used in manufacturing expansion joints and bellows. Even furnace components are manufactured using this alloy. Because of good thermal resistance, they are used in heat exchangers and heating element tubes. It is also used in spiral welded tubes for burner pipes and flues.
The grief of the consumer today
In the ever increasing competition, it is the quality of goods and services that is degrading at an alarming rate. It affects no one but the customer. The customers find themselves struggling with high commission, and poor quality of the supplied material. They are often lost after the delivery of products, as they have no one to attend to their after sales grievances. There are often no mill reports to guarantee the good quality of products. The material is often very hard to be put to use and yields under high pressure.
The goods take forever to be delivered and when they are, they tend to lose their economic value on account of poor, unprofessional packaging. Sometimes, to worsen the situation, wrong grades are supplied. Scrap material is supplied without proper treatment. That often leads to increase in rejection rates. There is no control on quality and testing. The growing distress amongst the consumer is an example of the darker side of the market. In the midst of false claims and promises, it is the customer who ends up in severe losses.
