The master link Grade 100 is forged by special grade 100 alloy steel with high intensity and high toughness, and then it is heat treated. It can be matched with grade 100 chains and riggings.Grade 100 steel is known for its exceptional strength, typically exhibiting a minimum yield strength that's significantly higher than lower-grade steels, such as Grade 80.This higher strength allows Grade 100 steel chains and components to handle heavier loads and endure more stress without failing.
