厚度不大於6mm薄板材，高效落料模。沖載模及壓印模各種剪刀、鑲嵌刀片、木工刀片螺紋軋制模和耐磨滑塊冷鐓模具，熱固樹脂成型模，高級量規等深拉成型、冷擠壓模具。

SKD11使用方法（僅供參考)

1.“淬火+回火”狀態下使用

2.“淬火+冷處理+回火”狀態下使用（適於高精度與尺寸穩定要求）

3.“淬火+回火+氮化處理”狀態下使用（適於表面高硬度要求）

4. 深冷處理 為獲得最高硬度和尺寸穩定性，模具在淬火後立即深冷-70至-80℃，保持3-4小時，然後再回火處理，經深冷處理的工具或模具硬度比常規熱處理硬度高1-3HRC。 形狀復雜和尺寸變化較大的零件，深冷處理有產生開裂的危險。

5. 氮化處理 模具或工件氮化處理後，表面形成一層具有很高硬度和一定耐蝕性的硬化組織。

6. 在525℃氮化的處理，工件表面硬度約為1250HV，氮化時間對滲層影響如下表所示。氮化時間（小時） 20 30 60 滲氮層深度mm 0.25 0.30 0.35

7.在570℃軟氮化處理，工件表層硬度約為950HV。通常軟氮化處理2小時，硬化層深度可達到10-20um. 磨削加工模坯或工作在低溫回火狀態，磨削容易產生磨削開裂。為防止裂紋發生應采取小的磨削進給量多次磨削，同時輔加良好的水冷條件。

線切割加工形狀復雜或尺寸較大的模具，最終成行采用線切割加工時，通常會遇到開裂現象發生。

為防止開裂，建議采用氣淬及高溫回火處理，以降低熱處理應力，或對模胚進行腔預加工處理。
