Profile: Dinesh Tube (India) specializes in manufacturing and supplying of stainless steel products. We can arrange chemical, physical, mechanical, ultrasonic, micro, IGC and any other related test from govt. approved laboratories. Hastelloy B2 Tube is solid strengthened and molybdenum-nickel alloy with significantly resistant to the reducing atmosphere like sulfuric, acetic and phosphoric acid and hydrogen chloride gas. Molybdenum is the main alloying element that providing corrosion resistant to the reducing atmosphere. This alloy in as-welded condition can be used that is because it resists grain boundary carbide precipitation formation at the weld heat affected area. Grade R60702 is a zirconium material unalloyed. It is also known as Zirconium 702 which has high content of zirconium. It is a metal that has a high affinity for oxygen that makes it useful in the formation process of an oxide layer. The layer is formed in room temperature. The tubes made out of this grade are available in different size and specifications.
