Nitrided steel base plate with excellent corrosion resistance and production method

Abstract

A nitrided steel base plate with excellent corrosion resistance comprises, by weight percent, 0.010%-0.10% of C, 0.10%-1.00% of Mn, 0.010%-0.10% of Si, smaller than or equal to 0.02% of P, smaller than or equal to 0.01% of S, 0.50%-1.50% of Als, smaller than or equal to 0.005% of N, 0.10%-1.50% of Cr, 0.01%-1.00% of Cu and 0.01%-1.00% of Ni. A production method comprises the preparing steps of melting and continuous casting blank forming, cast blank heating, hot rolling, reeling, cold rolling, annealing and flattening. Steel used for a traditional iron pan serves as a base body, and rusting can be effectively avoided after nitriding treatment; the surface hardness is high, the corrosion resistance is excellent, the high-temperature performance is stable, and the fatigue resisting strength is high. After the low-carbon steel plate is subjected to the nitriding treatment, the low-carbon steel plate can replace stainless steel and functional coating steel plates to be used for manufacturing woks, corrosion resisting containers and the like.

Description

technical field [0001] The invention relates to a nitriding steel and a production method thereof, in particular to a substrate for nitriding steel with excellent corrosion resistance and a production method thereof. Background technique [0002] At present, the main materials for manufacturing woks are aluminum alloy, stainless steel, and iron. Aluminum alloy pans conduct heat quickly and are heated more evenly. However, when cooking acidic, alkaline or salty food, the aluminum in the pan will dissolve and pollute Food is not good for human health. The stainless steel pot has a beautiful appearance and has the characteristics of "physical non-stick" and "less oil fume", but the pot body is heavier and the price is more expensive. Traditional iron pots are cheap and do not contain other chemical substances. Even if a small amount of iron dissolves, it will not cause damage to the human body. On the contrary, it is also considered the most direct method of iron supplementati...
