Neil Metals, situated in Kolkata, India, is a well-known producer and supplier of **Hastelloy B2 Forgings**, offering high-performance forged products designed for severe chemical conditions. Built for strength and corrosion resistance, these forgings are finely crafted from superior quality material and sophisticated forging processes. Neil Metals guarantees every product to meet international standards, offering strength, reliability, and long life. Universally applied in **chemical processing, pharmaceuticals, heat exchangers**, and **waste treatment plants**, Neil Metals Hastelloy B2 forgings are relied upon for their consistency in harsh operating conditions.
**Hastelloy B2 Forgings** (UNS N10665) consist of a **nickel-molybdenum alloy** comprising about **68–71% Nickel** and **28–30% Molybdenum** with very small quantities of carbon, iron, and silicon. The composition ensures superior resistance to **hydrochloric acid** and a wide group of **non-oxidizing acids**. The forgings have **tensile strength of approximately 690–760 MPa**, **yield strength of more than 280 MPa**, and **superior ductility and impact resistance**. The forgings also increase grain structure further, enhancing mechanical properties under thermal and chemical stress.

**Hastelloy B2 Forgings** find extensive application in the manufacture of **pump shafts, valve bodies, flanges, rings, reaction vessels, impellers, nozzles**, and **custom parts** subject to aggressive chemical media. Their high resistance to **pitting, stress corrosion cracking**, and **knife-line attack** renders them the first choice for **chemical reactors**, **evaporators**, **distillation columns**, and **heat exchangers**. They have particular compatibility with environments involving **hydrochloric, sulfuric, acetic, and phosphoric acids**. Due to their good weldability and thermal stability, Hastelloy B2 forgings are a reliable option for highly stressed, highly corrosive process duties.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
