Stainless steel wins hands down when it comes to sanitary needs. Whether it's sanitary valves, sanitary strainers, or sanitary clamps, it doesn't really matter. Stainless steel is extremely sanitary, as well as very durable. A stainless steel pipe has a lifespan of more than 100 years.
As with all steels, stainless steel is primarily composed of iron and carbon. Steel is made in two steps. First, iron ore is smelted in a blast furnace. Molten raw "pig iron" is blown with high purity oxygen in modern plants to reduce its carbon content. The other type of steel we’ll see in sanitary process are precipitation hardened martensitic or semi-austenitic steels.
A stainless steel metal product is the most hygienic option for any industry due to its ease of cleaning and self-healing surfaces. Stainless steel sanitary fittings are classified according to the three categories of vessels they may be constructed for: pipes, tubing, and hoses.
