Stainless steel and aluminum alloy which is good

If you look at the characteristics, aluminum alloy material density is relatively low, but the strength is relatively high, and stainless steel material corrosion resistance is relatively strong, resistance to welding performance is relatively good. If it is from the hardness to consider, stainless steel material strength is higher, at least the hardness is better than aluminum alloy. If it is from the high temperature performance to consider, stainless steel can be high temperature, because the melting point of stainless steel can be up to 1500 degrees, aluminum alloy, there is no way to withstand too high a temperature, the melting point of the highest can only be up to} 800 degrees or so, so it depends on which angle to look at.

Stainless steel 316 or 304 good?

Stainless steel 316 is better. 316 stainless steel oxidation resistance, corrosion resistance than 304 to be stronger, and 316 stainless steel in 304 based on the addition of molybdenum, greatly enhancing its waterproof performance, at the same time it is much more expensive than 304. Both stainless steel has been done to food grade, because 316 stainless steel is more expensive, so it is generally used for medical equipment tool making, 2304 stainless steel is cheaper, daily life everywhere in the home appliances and household containers are used 304 stainless steel, such as stainless steel bowls in the kitchen, pots and so on.

What is the difference between stainless steel 316 and 316L?

1, the two contain different chemical compositions, the standard grade of 316L is 022Cr17Ni12Mo2, the standard grade of 316 is 06Cr17Ni12Mo2, and there is a difference in the carbon content of the two.

2, corrosion resistance strength is different, the two compared to 316L corrosion resistance is stronger, because it is ultra-low carbon.

3, the degree of heat resistance of the two are different, 316's heat resistance is more excellent than 316L, because it is a little higher carbon content.

4, the two compared to 316L mechanical properties are better, under the same conditions, 316L protection is stronger, its price is relatively higher.
