Iso 20457 Tg5 [new] Access

: Not all materials can achieve TG5. Highly crystalline plastics with high shrinkage (like POM or PA) are harder to hold to TG5 than amorphous plastics (like PC or ABS). Manufacturing Method

ISO 20457 is a standard addressing technical requirements and classifications for specialized ferrous materials used in high-performance applications; within its classification system, the designation "TG5" identifies a specific grade with defined chemical, mechanical, and heat-treatment characteristics. TG5 is characterized by a controlled alloy composition that prioritizes a balance of strength, toughness, and wear resistance—attributes achieved through precise additions of carbon, chromium, molybdenum, and small amounts of other alloying elements, plus tightly specified impurity limits.
