Why do stainless steel sinks need to be annealed?

The most common materials used in the market to make stainless steel sinks are generally 201, 304, and 316. One important forming method is called integral stretching (also known as integral stamping or joint stretching). The integral stretching process is a process of directly stretching two groove bodies on a piece of material through a combination of molds. Whether it is a single groove or a double groove, the stretching during processing is generally divided into two stages. However, the integral stretching requires a high-temperature annealing solution heat treatment in the middle of the two stages to reduce hardness, prevent cracking, and facilitate subsequent processing. It can also improve the various properties of stainless steel material.

Kitchen Sink Bright Annealing Heat Treatment Process

After Annealing, Surface brightness and without oxidation.

Furnace Characteristic:

①Advanced temperature control : Intelligent thermostat, silicon-controlled rectifier and schneider electrical switches ensure temperature control precision of ±1℃;
②The heating hearth (muffle) is made of imported Sweden high-temperature resistance nickel alloy (310S);
③Heating elements: High-temp. resistance wire is used, with alumina tube frame; heating elements are arranged in an upper-lower removable to ease repair or replacing; replacing resistance wire has no impact on production;
④Protective gas: mixture (hydrogen 75% and oxygen 25%) decomposed from liquid ammonia gets into the hearth and reaches gas protection effect; Product surface will become brightness and won’t be oxidized after heat treatment.
