Stainless steel does not stain, corrode, or rust as easily as ordinary steel. Cast high alloy steels are widely used for their corrosion resistance in aqueous media at or near room temperature. Stainless steel is defined as a ferrous alloy with a minimum of 11% chromium content. Most cast stainless steels are more complex compositionally than this, typically containing one or more alloying elements in addition to chromium ( for example, nickel, molybdenum, copper, niobium, and nitrogen) to produce a specific microstructure, corrosion resistance, or mechanical properties for particular service requirements.
Service temperature provides the basis for selection of cast grades. Stainless material suited to tap casting does not need additional alloys specifically for excessively high temperature, strength, hardness, or chemically corrosive environments.
Stainless steel investment casting by the ” lost wax” method has been used for centuries to make useful and decorative, high precision tap and faucet in different sizes and weights. It can produce complicated shapes that would be difficult or impossible with die casting. Stainless steel casting process is generally more expensive than die casting or sand casting. This method is best suited to extremely high precision, low volume applications.
With the improvement of people’s living standard, the demand of water quality is gradually strengthened, as the important parts of the water tap is concerned. The iron tap and faucet are easy to produce embroidery after permanent, thus affecting the water quality, so the stainless steel castings become tap and faucet manufacturers preferred.
Stainless steel faucet is a simple bathroom products, is also very easy to be ignored, and the quality of water actually not only for convenience, the use of persistence, but also the relationship between the health problems, because the amount of precipitation of lead faucet is exceed the standard for drinking water safety is very important. At present, whether it is building materials market or network sales of faucet type is very much, so be sure to buy quality assurance safety taps, so that the whole family can enjoy safe drinking water.
The personage inside course of study thinks, faucet industry develops to this day, experienced cast-iron faucet, copper faucet, copper galvanization faucet three stages,but there has been no way to reduce lead levels. At present market, some of the faucet enterprises illegal use of copper scrap recovery, zinc alloy water, plastic products, lead content exceeded the standard, very serious, consumers must pay attention when purchasing. Choose health and safety faucets, mainly to see the heavy metals in the product, especially the precipitation of lead material.
Usually ordinary tap, casting lead content ratio between 3%-8%, tap if used for a long time, the material inside the lead metal may be released into the water. Drinking water can cause excessive lead content and lead damage, will not only affect the drinker’s intellectual growth, but also seriously affect the health, will be greater impact on children.The data indicate that severe lead contamination often endangers human reproductive capacity, renal function, and the nervous system.
With the development of science and technology and manufacturing process, it is possible to use the faucet manufacturing stainless steel. Stainless steel is an internationally recognized health material, no lead, and acid and alkali resistance, corrosion resistance, do not release harmful substances, the use of stainless steel faucet can ensure the health of human body health.
Stainless steel faucet manufacturing process in China gradually mature, whether in production or in grade, have greatly increased. Although at present in the domestic market share is small, but because of its health, environmental protection, durability and other characteristics, in recent years more and more favored by consumers, gradually seize the copper leading market share. Stainless steel faucet has become the development trend of bathroom industry at home and abroad. 95% taps are used in copper plating, stainless steel faucet is now popular, is a new trend of the market.
