Difference Between Hastelloy and Stainless Steel

Thekey differencebetween Hastelloy and stainless steel is thatHastelloy展示了一个杰出的腐蚀resistance compared to stainless steel.

Alloys are mixtures of different chemical elements, including metals as the major component and非金属as a minor component. Hastelloy and stainless steel are two such alloys which are well known for their excellent corrosion resistance. However, Hastelloy is considered to be more effective for the corrosion resistance than stainless steel due to its specific composition, which has more镍in it.

什么是Hastelloy?

Hastelloy is a nickel-based alloy which shows excellent corrosion resistance. We call it a superalloy because it can withstand high temperatures, high stresses, and often highly oxidizing atmospheres. This material is available in the form of plate, sheet, bar, pipe, tube, etc. Some important properties of this alloy are as follows:

Properties of Hastelloy

• High resistance to stress
• Outstanding corrosion resistance
• Excellent stress corrosion cracking resistance
• High resistance to acids
• Ease of welding
• Ease of fabrication
• High resistance to oxidation (at high temperatures)

首先，这种合金是由镍制成的，以及其他一些元素（例如铬和钼）中的一小部分。生产是一个复杂的过程，涉及将基本成分与多种化学元素的混合，例如钨，碳，钛，铝，铝，锰，铜，钴，铬等。制药行业等

What is Stainless Steel?

Stainless steel is an alloy of steel with a high chromium content. Therefore, it has great corrosion resistance. Typically, this alloy contains about 10.5% chromium and 1.2% carbon by weight of the alloy. With increasing chromium content, the corrosion resistance also increases. Moreover, the addition of some molybdenum into this mixture can increase the resistance against acids. Stainless steel is available in the forms of sheets, plates, bars, wires, tubes, etc.

不锈钢的生产过程有多个重要步骤：熔化和铸造，形成，热处理，下降，切割和修饰。此外，该生产的基本原材料是铁矿石，铬，硅，镍，碳，氮和锰。通过添加不同数量的这些元素，我们可以根据需要获得不同的属性。例如，添加更多的氮将增加拉伸强度。

Hastelloy之间的区别是什么and Stainless Steel?

Hastelloy is a nickel-based alloy which shows excellent corrosion resistance while stainless steel is an alloy of steel with a high chromium content and consequently a great corrosion resistance. Moreover, the key difference between Hastelloy and stainless steel is that Hastelloy shows an outstanding corrosion resistance in comparison to stainless steel. Moreover, the major components of Hastelloy are nickel, chromium and molybdenum while the major components of stainless steel are iron, chromium and carbon.

When considering the applications of these materials, Hastelloy is used in industries such as chemical processing industry, aerospace, pharmaceutical industry, etc. whereas stainless steel is used in architecture, plumbing, pulp and paper industry, chemical processing industry, food and beverage industry, etc.

概括– Hastelloy vs Stainless Steel

In brief, Hastelloy and stainless steel are alloy materials. Hastelloy is a superalloy while stainless steel is an alloy of steel. Both these are resistant to corrosion, but the extent of resistance is different from each other. In conclusion, the key difference between Hastelloy and stainless steel is that Hastelloy shows an outstanding corrosion resistance in comparison to stainless steel.
