Is Grade 304 or Grade 316 Stainless Steel Better For My Home?
  • In the world of stainless steel, we have many grades, differentiated based on their unique mix of iron and chronium at various levels and other additions as well for certain grades. The most common grades are Grade 304 and Grade 316 Stainless Steel.
  • Grade 304 is the most common variety of stainless steel, containing 17% chromium and 8% nickel. It is frequently used because of its versatility. Even among steel alloys, grade 304 stainless steel is noteworthy for its high tensile strength—roughly 621 MPa (90 ksi). Like most stainless steel, grade 304 has a high maximum operating temperature (about 870˚C). This combination of high tensile strength, temperature resistance, and corrosion resistance makes grade 304 stainless steel ideal for a wide variety of applications.
  • The 2nd most common steel alloys would be Grade 316 Stainless Steel, containing 16% chromium, increased nickel levels and has other additions like molybdenum in it as well. Grade 316 stainless steel has a high tensile strength of 579 MPa (84 ksi) and a maximum use temperature of around 800˚C (1,472˚F). While having a lower tensile strength and temperature tolerance than grade 304 stainless steel, grade 316 stainless has a better resistance to chlorides (like salt) than 304 alloy does. This makes it a preferred choice for any application involving exposure to salt or other chlorides.
  • Of course, we also have the most “overpowered” contender, the Grade 420 Stainless Steel. Infamously known for its Rank 1 in terms of hardness among all the stainless steel grades. It contains 12% chromium – 50HRC. Grade 420 offers good ductility and corrosion resistance, especially to alkalis, fresh water, foods, and mild acids. Cutlery is commonly made with grade 420 stainless steel due to its corrosion resistance, though pitting can occur with continued exposure to certain food substances.
  • Now background information aside, your dire question must be “Odoroku, what is the best Stainless Steel grade for general home goods then, Grade 304 or 316??”
  • To answer your burning question, there is actually no definite winner. Both are excellent in their own applications.  Grade 304 does well for appliances, kitchen equipment and decorative trim. Whereas, Grade 316 excels in commercial kitchen surfaces, equipment and appliances.
  • At Odoroku, our Dish Rack is made of 304 Stainless Steel while our Thermal Flasks are made of 316 Stainless Steel. We ensure that our steel products are within the right grade to cater to your wellbeing better.
  • Whenever you’re unsure of which Grade of stainless steel is preferred, you can always refer back to this guide before making a purchase.
