This alloy displays some remarkable properties. It exhibits the corrosion resistant property of stainless steel. Along with that, it provides an excellent resistance towards intergranular corrosion, which takes place after an exposure to temperatures in the range 800-1500 degree Celsius. In that temperature range, it successfully prevents chromium carbide precipitation. It also exhibits good toughness at low temperatures.
Stainless Steel 347 Round bars rods, the higher carbon version of this alloy, is majorly used where higher creep resistance is required. It also functions effectively at temperatures above 1000 degree Celsius.
Stainless Steel 347 Round bars rods can be easily welded and fabricated by standard methods. A post weld treatment is not required.
On account of all these remarkable properties, it has various applications in numerous industries. Like other stainless steel alloys, it is also used in making food and chemical processing equipment. These also form an important constituent of fluid catalytic cracking units in petroleum refineries. They are also used in polythionic acid service as they resist corrosion cracking. They are also suitable for usage in nitric solutions and prove to be useful in strongly oxidizing conditions too.
What are the problems faced by the customers?
Why do the consumers trust us?
Because we claim about supplying the best quality products after gathering proofs about the same. We have been certified by ISO 17025 Standards Laboratory on the quality of the alloys we produce and supply. Our mill reports are consistent with EN10204 NACE 3.1, NACE 3.2. We also get our products tested in government as well as private labs. Thus, a third party inspection also speaks in favor of our claims. As mentioned above, we keep our consumers from facing the problem of the unavailability of alloys through our policy of maintaining a constant stock. As soon as the material is dispatched to be transported to the customer, the other set is ready to replenish the stock immediately. This continuity is rarely broken. We are also known for our excellent after sales services. We never fail to extend a helping hand to our clients, even after the product has reached them. We have the fastest delivery service, giving utmost priority to urgent orders. Our team adopts professional packaging methods to ensure that the products reach our clients in their best form. We are available almost every time of the year to attend to the problems of our clients and fix them in the most effective manner. We specify the heat number on the raw material, so that the consumers can trace the history and application of the product. We are careful in supplying the right grade of the material, with proper level of hardness. The impeccable surface finish and appropriate hardness of goods has impressed customers not only in India, but in other countries too. We happily claim a rejection rate of less than one percent. Once chosen, we will always make each and every penny paid by the clients, count.
