What is the difference between grade 304 and 316 stainless steel?
The simple answer is 304 contains 18% chromium and 8% nickel while 316 contains 16% chromium, 10% nickel and 2% molybdenum. The molybdenum is added to help resist corrosion to chlorides (like sea water and de-icing salts).
What is the hardness of 304 stainless steel?
304 stainless steel plate has a minimum tensile strength of 75 ksi and a minimum yield strength at 0.2% of 30 ksi. 304 stainless steel plate has an elongation of 40%. This type of stainless steel plate has a maximum Brinell hardness of 201 and a Rockwell B hardness of 92.
Is 316 stainless steel surgical grade?
It is the addition of chromium that gives the steel its unique stainless, corrosion-resisting properties. Austenitic 304 and 316 stainless steels are considered surgical or medical-grade stainless steels, they are the most commons stainless steels.
Can 316 SS be heat treated?
316 stainless steel cannot be hardened by heat treatment. Solution treatment or annealing can be done by rapid cooling after heating to 1010-1120°C. edges cause excess work hardening.
What is better 304 or 316 stainless steel?
Grade 304 is typically more affordable than Grade 316. Here are some situations where 316 stainless steel may be the better choice: The environment includes a high amount of corrosive elements. The material will be placed underwater or be exposed to water consistently. In applications where greater strength and hardness are required.
What is the difference between 304 and 316 stainless?
A major difference between 304 and 316 stainless steel is the chemical composition, with 316 containing a significant amount of molybdenum ; typically 2 to 3 percent by weight vs only trace amounts found in 304.
What is density of 304 grade stainless steel?
The density of 304 and 304L stainless steel plate is 0.285 Ibm/In3 at 68 ℉. The thermal conductivity of grade 304 and 304L stainless steel plate is 9.4 BTU/ h ft. at 212 ℉ and at 932 ℉ the thermal conductivity is 12.4 BTU/ h ft.
Stainless Steel 304 Capillary tube can be either harddrawn (hardness 260-330 HV) or annealed (hardness <180 HV).
