1. Nickel based alloy Introduction

• Incoloy alloy is a nickel based corrosion-resistant alloy of the iron chromium series. It has good corrosion resistance in reducing and oxidizing acids, as well as good resistance to stress corrosion cracking, pitting, and crevice corrosion. Commonly used materials in chemistry, petrochemicals, nuclear industry, and rare metal extraction include incoloy800, incoloy825, incoloy926, etc.
• Inconel alloy is a nickel, chromium, and iron solution strengthening alloy with excellent high-temperature corrosion resistance and oxidation resistance, as well as excellent cold and hot processing and welding performance. It is widely used in aviation, chemical, paper industry, and other fields. Commonly used ones include inconel600 inconel601 inconel625 inconel617 inconel718 inconelx750, etc.
• Hastelloy alloy is a nickel based corrosion-resistant and high-temperature alloy, mainly divided into two categories: nickel chromium alloy and nickel chromium molybdenum alloy. It has good corrosion resistance and thermal stability, and is commonly used in aviation, petrochemical, chemical fields, etc. Commonly used include Hastelloy C276, Hastelloy C22, Hastelloy b2, Hastelloy b3, Hastelloy C4, Haynes 230, Haynes 188, etc.

2. Hastelloy C4 Pipe Fittings

• Material

HastelloyC-4 is an austenitic low-carbon nickel molybdenum chromium alloy. The main difference between Nicrofer 6616 hMo and other early developed alloys with similar chemical compositions is their low carbon, silicon, iron, and tungsten content. This chemical composition gives it excellent stability at 650-1040 ℃, improving its resistance to intergranular corrosion. Under appropriate manufacturing conditions, it can avoid sensitivity to edge corrosion and corrosion in the heat affected zone of the weld.
The characteristics of HastelloyC-4 are:
Has excellent corrosion resistance to most corrosive media, especially in the reduced state.
Has excellent resistance to local corrosion in halides.
