<h2>概述</h2>
<p dir="auto">SUS304 是最常用的通用奥氏体不锈钢，无磁性，耐腐蚀性能好，广泛用于厨具、医疗器械等行业，冲压加工回弹比碳钢大。</p>
<h2>性能参数</h2>

<ul>
<li>耐腐蚀性能优异，长期使用不生锈</li>
<li>无磁性，适合特殊场合</li>
<li>延伸率好，冲压成型性不错</li>
</ul>
<p dir="auto"><img src="https://forum.mj7.cn/assets/plugins/nodebb-plugin-emoji/emoji/android/274c.png?v=ri5u9ft48ro" class="not-responsive emoji emoji-android emoji--x" title=":x:" alt="❌" /> <strong>缺点</strong>：</p>
<ul>
<li>价格比碳钢高 2 ~ 3 倍</li>
<li>回弹比碳钢大，模具需要做回弹补偿</li>
<li>切削加工性不如碳钢，模具磨损快</li>
</ul>
<h2>适用场景</h2>
<ul>
<li>厨具餐具</li>
<li>医疗器械</li>
<li>汽车排气系统零件</li>
<li>耐腐蚀要求高的冲压件</li>
</ul>
<h2>冲压要点</h2>
<ul>
<li>回弹比碳钢大，模具设计必须加回弹补偿</li>
<li>模具硬度要够，推荐 Cr12MoV 以上模具钢</li>
<li>冲压间隙比碳钢适当放大，减少粘模</li>
</ul>
