Chemical Processing Industry Hastelloy C4 Pipe 690 MPA Resistant To Stress Corrosion Cracking

Product Introduction

Hastelloy C4 pipe is a high-performance nickel-based alloy pipe with excellent corrosion resistance and high temperature stability, which is widely used in the chemical processing industry. Its main chemical components include nickel (Ni) 60-70%, chromium (Cr) 14-18%, molybdenum (Mo) 14-17%, iron (Fe) 3-7%, etc. These components give it excellent tolerance to a variety of acidic media, chlorides and other corrosive media in oxidizing and reducing environments. The physical properties of Hastelloy C4 pipe include density 8.64 g/cm³, melting point 1325-1370°C, tensile strength 760 MPa, yield strength 345 MPa, and elongation 50%. This alloy pipe can still maintain good mechanical properties and oxidation resistance in high temperature environments, and is suitable for the manufacture of chemical reactors, heat exchangers, distillation towers and other equipment. It has good processing performance and can be formed by conventional welding, cold rolling, hot rolling and other processes, and is suitable for the manufacture of parts with complex structures. Hastelloy C4 pipe has strict implementation standards and complies with ASTM B575 and ASME SB575 standards, ensuring its wide application in chemical, petroleum, aerospace and other fields.

Parameter

Specific Applications

1. Reactors and Agitators: Used in the manufacture of reactors and agitators that handle corrosive chemicals such as strong acids, such as sulfuric acid, hydrochloric acid, acetic acid, etc. Hastelloy C4 performs well in these environments and is able to resist uniform corrosion and stress corrosion cracking.
2. Piping Systems: Used in piping systems for the transportation of corrosive chemicals, its good corrosion resistance and welding properties make it an ideal material choice.

Advantages and Characteristics

• High strength and toughness: Hastelloy C4 pipe has a tensile strength of 650 MPa, a yield strength of 280 MPa, and an elongation of 40%. It has high strength and good toughness and can withstand large operating pressures and temperatures.
• Good ductility: It has good ductility and is easy to process and form, suitable for various processing processes such as forging, hot rolling, cold working and welding.
• Good machinability: Hastelloy C4 pipe has good machinability and can be forged, hot upsetting and impact extruded by a variety of methods. Although the alloy is easily work-hardened, it can be successfully spun, deep drawn, pressed or punched after proper treatment.
• Excellent weldability: Hastelloy C4 pipe can be welded by various welding processes such as tungsten electrode inert gas shielded welding, plasma arc welding, manual sub-arc welding, metal inert gas shielded welding and melt inert gas shielded welding. For the best welding results, it is recommended to use pulse arc welding and ensure that the material is in an annealed state before welding.
