Stainless steel is steel that has a mixture of chromium is a chemical preservatives. Chrome is the ability to resist corrosion by surface oxide chromium films protect the skin but when it gets hot, and for a long time. Cause chromium carbide bit of the edge Affect the corrosion resistance of stainless steel is reduced. This project is intended to study the impact of chromium carbide that affect resistance to corrosion, mechanical properties of stainless steel AISI 304 Australia, new 304H Semitic, 321H and 316 from baking to achieve the test piece of chromium carbide based on bit boundaries. By baking at the temperature the temperature is 3 O O 550 650 750 Gonzalez Gonzalez, and Gonzalez O. Baking time: plating is divided into 3 periods: 2, 4, and 6 hours and then leave to cool in the air. Bring check comma structure using a color etching acid Chromium deficiency tests using a technique of pouring nathi mik's video. The yoke's Vegas mansion Mechanical properties test using a Vickers hardness test and tensile test. From studies examining comma structure. The size of the fine grains of different sizes? Test piece 304 more high temperature and long time. A higher percentage of chromium deficiency by increasing the temperature and time. 304H test piece temperature O 550 and 650 O Gonzalez. High temperatures and long time. The lack of a higher percentage of chromium, but temperature 750 O Gonzalez. The minimum percentage of chromium deficiency test piece 321H percent lack of chromium occur? Test piece sections 316 percent chromium deficiency does not occur at all. Effect of chromium deficiency that affects the mechanical properties: hardness values have different value. But the tensile strength permanently expanded to have a relationship with the lack of a clear, chrome is even more chrome is missing percent tensile strength values are permanently expanded to fall in all three pieces.
