Pengertian Baja Tahan Karat 316 Paduan

Baja Tahan Karat 316 belongs to the austenitic family of stainless steels and contains molybdenum — an alloying element that significantly enhances resistance to korosi yang disebabkan oleh klorida.

Komposisi Kimia Khas:

Kromium (Kr): 16.0–18,0%
Nikel (Di dalam): 10.0–14,0%
Molibdenum (Mo): 2.0–3,0%
mangan (M N): ≤ 2.0%
Karbon (C): ≤ 0.08%
Silikon (Dan): ≤ 1.0%
