فولاد ضد برش مورد استفاده در روکش قفلهای ضد برش

آهن مذاب تصفیه شده را با افزودن مقدار معین کربن و فلزهای آلیاژ دهنده مثل وانادیم، کروم، تیتانیم، منگنز و نیکل به فولاد تبدیل می‌کنند. فولادهای ویژه ممکن است مولیبدن، تنگستن یا فلزهای دیگر داشته باشند. این نوع فولادها برای مصارف خاصی مورد استفاده قرار می‌گیرند. در دمای زیاد، آهن و کربن با یکدیگر متحد شده، کاربید آهن (Fe۳C) به نام «'سمنتیت» تشکیل می‌دهند. این واکنش، برگشت‌پذیر و گرماگیر است:قفل ضدبرش

  • Fe۳C <------- گرما + ۳Fe + C

هرگاه فولادی که دارای سمنتیت است، به کندی سرد شود، تعادل فوق به سمت تشکیل آهن و کربن، جابجا شده، کربن به صورت پولکهای گرافیت جدا می‌شود. این مکانیزم در چدن‌ها که درصد کربن در آنها بیشتر است، اهمیت بیشتری دارد. برعکس، اگر فولاد به سرعت سرد شود، کربن عمدتاً به شکل سمنتیت باقی می‌ماند. تجزیه سمنتیت در دمای معمولی به اندازه‌ای کند است که عملاً انجام نمی‌گیرد.

شایان ذکر است که واژه ضدبرش که در قفلها استفاده میگردد، در مقابل اره آهن بروقیچی های آهن بر ازخود مقاومت نشان میدهند ودر مقابل فرزبرش وهوابرش آسیب پذیر هستند.
