304 stainless steel performance is better than 202 stainless steel, the price is more expensive than 202 stainless steel.
They all belong to the austenitic stainless steel, 202 with Mn and N to replace part of nickel, so as to obtain the mechanical properties and good corrosion resistance, is a new type of stainless steel nickel, his strength at room temperature is higher than 304, there are no good oxidation resistance and magnetic strength in medium temperature below 800 degrees. Potions don't fly
304# and 202# are American Standard grade 304 is 0Cr18Ni9202shi 1Cr18Nn8Ni5N
Not bad money to use 304 of the durability, a few years later, if the price increases, maybe scrap can sell back the cost of moneyIdentification: the only way for you is to go to Taobao to buy potions and estimate where your hardware parts might be soldOther methods are not good, the naked eye can not tell, we are not able to distinguish between the industry are relying on syrup202 can also be used but a guarantee and profiteers will give you for 201 anyway you do not201 did not rust for 2-3 years
