Product Description

UNS S66286, AISI 660, AMS 5731, ASTM A 638 stainless steel rod

The alloy A-286 is designed for applications requiring high strength and excellent corrosion resistance at temperatures up to 704 ° C.
A-286 cut section of the toughness is very good. In fact, the A-286's cut-out fracture strength is superior to other commercial alloys with similar high-temperature properties. One of the great advantages of this material is that it can achieve the effect of precipitation hardening and strengthening by heat treatment.

Application:
The alloy 400 is widely used and is mainly used in marine and chemical treatment environments. The main uses include valves, pumps, pump shafts, drive shafts, marine fixtures and fasteners, chemical treatment equipment, gasoline cylinders, water tanks, crude oil distillation, , Pipes, boiler feed water heaters, heat exchangers, oxygen scavengers and so on.
Corrosion resistance
Alloy 400 does not produce chloride stress corrosion cracking. In general, alloy 400 in the reduction environment corrosion resistance is good, but in the oxidation environment, corrosion resistance is poor.
In the normal temperature and high temperature environment, alloy 400 resistant to a variety of corrosion, including the vast majority of alkaline substances, salt, water (including salt water), food, organic matter.
But the material can not be used for strong oxidizing acids such as nitric acid and nitrous acid
Alloy 400 can tolerate less than 80% sulfuric acid and less than 20% hydrochloric acid.
The alloy 400, which is harmless to the alloy 400, may also cause corrosion of the alloy 400 if it contains oxide impurities such as ferric chloride, iron sulfate, chromate, nitrate, peroxide and copper.
