The difference between stainless steel 316 and 304 of Saddle Pipe Clamp

Saddle Pipe Clamps is used to fix iron pipe or other pipeline. The two most commonly used stainless steels are 304 and 316 (or 1.4308 and 1.4408 corresponding to German/European standards).

The material of Saddle Pipe Clamp is determined by the use environment of pipe clamp. Generally, stainless steel pipe clamp is widely used. The main difference in chemical composition between 316 and 304 is that 316 contains Mo and is generally considered to have better corrosion resistance.

It has better corrosion resistance than 304 in high temperature environments. Therefore, in high temperature environments, engineers usually choose 316 material components. But the so-called nothing is absolute, in the concentrated sulfuric acid environment, no matter how high the temperature, do not use 316! Otherwise, the matter may be important.

[1] Mo is indeed a high temperature resistant material (you know what the crucible used to melt gold is? Molybdenum crucible! .

[2] Molybdenum reacts readily with high-valent sulfide ions to form sulfides. Steel reacts with other substances.

304 stainless steel is a general purpose stainless steel material that is more rust resistant than 200 series stainless steel materials. It is also better resistant to high temperatures, which can be as high as 1000-1200 degrees. 304 stainless steel has excellent stainless steel corrosion resistance and good resistance to intergranular corrosion. 304 stainless steel has strong corrosion resistance. It also has good corrosion resistance to alkali solutions and most organic and inorganic acids.

As a widely used steel, has good corrosion resistance / heat resistance, low temperature strength and mechanical properties; stamping / bending and other hot workability, no heat treatment hardening phenomenon (non-magnetic, use temperature Curtis -196 ℃ ~ 800 ℃ easy to use).

Uses: household goods (1/2 class tableware/cabinet/indoor plumbing/water heater/boiler/barrel), auto parts (wiper/muffler/molded products), medical equipment, building materials, chemical industry, food industry, agriculture, marine parts.
