High-hardness scratch-resistant stainless steel, stainless steel water tank and preparation method thereof
The invention discloses high-hardness scratch-resistant stainless steel, a stainless steel water tank and a preparation method thereof. The high-hardness scratch-resistant stainless steel comprises chemical components including, by mass, 16.0-18.0% of Cr, 3.0-6.0% of Ni, 4.0-7.0% of Mn, 0.5-1.0% of Cu, 0.35-0.6% of N, 1.1-1.5% of Mo, 0.05-0.15% of Si, 0.1-0.3% of Al, 0.1-0.3% of W, less than or equal to 0.03% of C, less than or equal to 0.045% of P, less than or equal to 0.03% of S, one or more metamorphic elements selected from B, Nb, Ti and RE and the balance Fe and inevitable impurities, wherein the content of B is 0.001-0.01%, the content of Nb is 0.01-0.1%, the content of Ti is 0.01-0.1%, and the content of RE is 0.02-0.5%. A stainless steel plate is blanked, bent and welded to be manufactured into a water tank base body, a rough surface of a micro-nano structure is obtained through two times of shot blasting treatment, the rough surface is coated with a high-abrasion-resistance nano coating, and the scratch-resistant stainless steel water tank easy to clean is obtained. The obtained stainless steel water tank not only has a scratch-resistant effect, but also has the properties of corrosion resistance, easiness in removing oil stains and the like.
本发明公开了一种高硬度耐刮不锈钢、不锈钢水槽及其制备方法。高硬度耐刮不锈钢化学成分按质量百分比为：Cr：16.0‑18.0％，Ni：3.0‑6.0％，Mn：4.0‑7.0％，Cu：0.5‑1.0％，N：0.35‑0.6％，Mo：1.1‑1.5％，Si：0.05‑0.15％，Al：0.1‑0.3％，W：0.1‑0.3％,C≤0.03％，P≤0.045％，S≤0.03％,选自B、Nb、Ti及RE中的一种或多种变质元素，且所述元素的含量为B：0.001‑0.01％，Nb：0.01‑0.1％，Ti：0.01‑0.1％，RE：0.02‑0.5％，其余为Fe及不可避免的杂质。将上述不锈钢板材下料、弯折和焊接后制成水槽基体，经两次喷丸处理获得微纳米结构的粗糙表面，并涂覆一层高耐磨纳米涂层得到耐刮易清洁不锈钢水槽。得到的不锈钢水槽既获得了耐刮擦效果，又具备耐腐蚀和油污易清洁等性能。
