product Alloys for Internal Combustion Engine Valve Applications - Specification
certification BIS ISI Certification
Standard IS 7494 : 2023
description Alloys for internal combustion engine valve applications are meticulously engineered materials designed to withstand the demanding conditions within the engine environment. These alloys generally comprise high-temperature resistant metals such as stainless steel, cobalt-based superalloys, or nickel-based alloys, which offer excellent heat resistance, corrosion resistance, and mechanical properties under extreme temperatures and pressures. The choice of alloy depends on various factors, including the engine type, fuel type, operating conditions, and performance requirements. For example, austenitic stainless steels are commonly used for their excellent corrosion resistance and high-temperature strength in gasoline engines, while cobalt-based superalloys like Inconel are preferred for their exceptional high-temperature strength and oxidation resistance in diesel engines and high-performance racing engines. These alloys undergo precise manufacturing processes such as casting, forging, and heat treatment to achieve the desired mechanical properties, dimensional accuracy, and surface finish, ensuring reliable performance and longevity of engine valves in demanding automotive and industrial applications.
