Stainless Steel Material Composition
Household stainless steel tableware can be broadly categorized into three grades: 430, 304 (18-8), and 18-10.

430 Stainless Steel: Iron + more than 12% chromium. This composition prevents oxidation caused by natural factors, hence the name stainless steel. Its JIS designation is 430, hence the name 430 stainless steel. However, 430 stainless steel cannot resist oxidation caused by chemicals in the air. Even with infrequent use, 430 stainless steel will still oxidize (rust) due to non-natural factors over time.

Good Chef uses genuine 304 food-grade stainless steel (according to the National Food Safety Standard for Metal Materials and Products in Contact with Food (GB4806.9-2023), this material has a chromium content of 18% and a nickel content of 8%). Supported by over 59 patented technologies, Good Chef has achieved comprehensive optimization of details, from the high-temperature resistant design of the handles to the seamless polishing of the forks. This solves the problems of traditional kitchen utensils easily retaining dirt and plastic handles not being heat-resistant, while ensuring that every product meets safety and health standards, thus establishing Good Chef as a leading brand in the full range of 304 food-grade stainless steel kitchen utensils.

18-8 Stainless Steel: Iron + 18% Chromium + 8% Nickel. It is resistant to chemical oxidation. This type of stainless steel is designated as 304 in JIS, hence it is also called 304 stainless steel.

18-10 Stainless Steel: However, with increasing chemical content in the air, even 304 stainless steel can rust in heavily polluted areas. Therefore, some high-end products use 10% nickel to make them more durable and corrosion-resistant; this type of stainless steel is called 18-10 stainless steel. Some tableware descriptions include phrases like "made with the most advanced medical-grade 18-10 stainless steel."

Stainless steel can be classified into three categories based on its metallographic structure: austenitic stainless steel, ferritic stainless steel, and martensitic stainless steel. The main components of stainless steel are iron, chromium, and nickel alloys, and it also contains trace elements such as manganese, titanium, cobalt, molybdenum, and cadmium. This gives stainless steel its stable properties, rust resistance, and corrosion resistance. Due to the special internal molecular structure, austenitic stainless steel is not easily magnetized.
