Pathan Durgadevi Udyan, Ground Floor, 25 Plot No 74/80, Patra Chawl, Maruti , Mandir Marg, Second Street, Girgaon, Mumbai, Maharashtra 400004There are several high-performance fastening solutions that we at Tubotech, a leading piping and tubing manufacturing company in India offer your business. One prime example is high-quality Hastelloy c276 fasteners. We have engineered them with such ‘Precision’ that they provide ‘High Corrosion Resistance’ and ‘Durability’ even when used under a hostile environment.
More importantly, we have designed Hastelloy c276 fasteners using a high-quality ‘Nickel-Molybdenum-Chromium’ superalloy. Hence the component is capable of resisting strong oxidizers, reducing agents, and chloride-rich atmospheres.
Our major goal at Tubotech, a top piping and tubing manufacturing company in India is to offer your business Hastelloy c276 fasteners which comply with international standards. These include ASTM B574, B574M, DIN, and ISO. Also, we seek to ensure that our fastening solutions provide for your business long-term performance, safety, and durability.
