Features:
1) pure and precision mirror polishing
2) strong corrosion resistance and its pitting corrosion goes beyond S-136 and 1.2316
3) convenient heat treatment, quenched and tempered steel after pre-hardened, its dimension become more stable.
4) its resistance is as good as S-136 and 1.2316, and easy to repair welding.
