Most of us understand that 304 as well as 316 are one of the most preferred and widely used investment casting key ins a stainless-steel factory. From the nude eye, it can be exceptionally challenging to tell the difference between them. But when selecting 304 or 316 stainless steel for casting, we need to recognize the distinctions between these 2 stainless steel kinds.
304 Stainless Steel Spreading
Grade 304 stainless steel is usually considered one of the most usual austenitic stainless-steel spreading kind. It consists of high nickel material that is typically between 8 and 10.5 percent by weight as well as a high amount of chromium at about 18 to 20 percent by weight. Various other significant alloying aspects consist of manganese, silicon, and carbon. The remainder of the chemical composition is mainly iron.
For the high amounts of chromium and nickel, 304 stainless steel castings have superb corrosion resistance. Common applications of 304 stainless-steel castings include:
Meat mincer accessories
Valve Housing
Pipe installations
Shutoff Elements
Automotive Parts
And so forth
316 Stainless Steel Spreading
Like 304 stainless steel, Grade 316 stainless steel has high quantities of chromium and nickel. Besides, silicon, manganese, and carbon, with most of the composition being iron, are additionally included in 316 stainless-steel. The significant difference between 304 and also 316 stainless-steel is that 316 consisting of a considerable amount of molybdenum, which is lacked in 304. The added molybdenum content in 316 stainless steel results in an increased rust resistance, that is why 316 stainless-steel castings are extra deterioration resistant than 304 stainless steel castings.
316 stainless steel is commonly taken into consideration among one of the most ideal choices when choosing an appropriate stainless-steel spreading quality for marine applications. Typical applications of 316 stainless steel castings include:
Chemical processing equipment parts
Clinical device elements
Marine hardwares
And more
Distinction Between 304 as well as 316 Stainless Steel Spreading
The most basic difference between 304 stainless-steel spreading and 316 stainless-steel spreading is that 316 stainless-steel spreading consists of even more nickel and also a little bit of molybdenum component. The general mechanical homes of both metals are mostly similar.
The raised nickel web content and the addition of molybdenum in 316 stainless-steel shows much better chemical resistance than 304 stainless steel. This difference makes 316 stainless-steel stand up to acids and also chlorides, including salt, therefore 316 stainless-steel spreadings are perfect for chemical handling as well as aquatic applications.
Nonetheless, the boosted nickel as well as added molybdenum likewise makes 316 stainless-steel castings a lot more costly than 304 stainless steel spreadings
In addition, when casting 304 stainless steel, the melting point is a little bit higher than that of casting 316 stainless-steel. The melting variety of 316 stainless-steel spreading is 2,500 ° F-- 2,550 ° F (1,371 ° C-- 1,399 ° C), about 50 to 100 degrees Fahrenheit less than the melting point of 304 stainless-steel spreading.
Though the 304 stainless steel spreading has a higher melting point, 316 stainless stee spreading has a far better resistance to chemicals and also chlorides (like salt) than 304 stainless-steel spreading. When it involves applications with chlorinated remedies or exposure to salt, 316 stainless steel spreadings are considered superior.

Even if recognizing the difference between 304 as well as 316 stainles steel casting, buyer or developer might still question whether to select 304 or 316 stainless steel as the casting product. If the stainless steel casting part collaborates with a very effective corrosives or relies on chlorides, after that 316 stainless-steel spreading is certainly worth it. In such woking setting, 316 stainless steel castings will certainly last longer than 304 stainless-steel castings.
However, for applications utilizing milder acids or
