304不锈钢：通用选择与广泛应用

304不锈钢是一种最常见的合金材料，它含有大约18%的钛元素，这使得其具有良好的耐腐蚀性和抗氧化性能。这种类型的不锈钢可以在室温下与多数化学物质接触而不会发生腐蚀，尤其适用于食品加工、制药、化工等行业。

食品级设备：由于其非磁性和无毒特性，使得304不锈钢成为了食品级设备制造中不可或缺的一部分，如厨房设施、餐具等。

化学处理器：在化学工业中，304不锈钢被广泛用于制造反应釜、管道系统和其他涉及强酸和碱处理的大型设备。

医疗器械：医疗环境对洁净度要求极高，304不锈鋼因其耐久且易于清洁的特性，在医用器械生产中占据重要地位。

321 不锈钢: 高温稳定性的优势

321 不锈钢是另一种常用的合金，不同于 304，它含有添加了3%钽（Ti），这使它比 304 有更好的高温稳定性。321 在高温度下表现出较低的碳扩散率，从而减少了氮气聚集现象。这对于需要长时间工作在高温环境中的应用非常有利，比如火力发电厂、高炉烟囱等场所。

火力发电厂部件：由于能承受较高温度而保持结构完整，321 不锈steel 是造火力发电厂部件如支架板、中间隔板以及热交换器的一流选择。

热处理工具：321 的耐热性能也使它成为热处理工具制作过程中的理想材料，如熔炼爐体、加热爐体及其他各种铸造工具等。

322 Stainless Steel: High Strength and Corrosion Resistance

The addition of titanium in the form of TiO to the stainless steel alloy gives it a higher strength and corrosion resistance than other grades. This results in a more durable material that can withstand extreme temperatures without losing its properties.

Chemical Processing Equipment: The high strength-to-weight ratio makes 322 stainless steel an ideal choice for chemical processing equipment, such as reactors, tanks, and pipes.

Marine Hardware: Its excellent corrosion resistance against seawater makes this grade suitable for marine hardware applications like propeller shafts, fasteners, and fittings.

Aerospace Industry: Due to its exceptional mechanical properties at high temperatures and low temperature impact toughness, 322 stainless steel is used in various aerospace applications including aircraft engines components.

Automotive Components: It is also used in automotive parts such as exhaust systems due to its ability to withstand high temperatures without compromising on performance or durability.

Piping Systems: The combination of strength and corrosion resistance makes it suitable for piping systems handling aggressive fluids or chemicals within the process industries like oil refining & petrochemicals
