Flange Bolting Washers
Creating a strong foothold in the industry, International Industrial Springs is innovating some of the most spectacular array of Belleville spring designs. They are manufactured in a OD/ID ratio which would fit standard flanges with ease. These washers which we provide forbid any bolt tension reduction which is caused due to-
• Differential Thermal Expansion
• High Temperature Bolt Creep
• Packing and Gasket Relaxation
• Vibration.
The main component which is used to develop such a commodity is the H13 steel tool, which has an operating temperature of roughly 1000°F. Other materials which we offer include- 17-7 PH Stainless Steel and INCONEL 718 and X-750 Alloys. Available in the PSI stress level of 30,000, 4000, and 60,000, one can choose these products as per their machinery requirements.
H13 Tool Steel is the main material for this product group, with a working temperature to 1000°F. Materials, such as 17-7 PH Stainless Steel and INCONEL 718 and X-750 Alloys, are also available. H13 flange bolting is available at 30,000, 4000, and 60,000 psi bolt stress.
