The combination of the booted 416 pins & blocks with yokes machined from 303 or 316L stainless steel provides a good material pairing that can withstand highly corrosive conditions. AISI 420 [1.4021/1.4028] The AISI 420 [1.4021/1.4028] is also a martensitic, magnetic steel. Due to its higher Chromium content, this material provides higher ...

This decreases the corrosion resistance of g rade 303 stainless steel to less than that for 304. However corrosion resistance remains good in mild environments. In chloride containing environments over 60°C, g rade 303 stainless steel is subject to pitting and crevice corrosion. Grade 303 stainless is not suitable for use in marine environments.

A312/A312M Standard Specification for Seamless, Welded, and Heavily Cold Worked Austenitic Stainless Steel Pipes.
