Precision Casting suppliers Introduction聽 The mechanical properties of ss 304 investment casting are higher than those of cast iron, but their casting properties are worse than those of cast iron. Due to the high melting point of stainless steel precision casting, molten steel is easy to oxidize, and has poor fluidity and large shrinkage. Its body shrinkage rate is 10-14%, and the linear shrinkage rate is 1.8-2.5%. In order to prevent defects such as insufficient pouring, cold insulation, shrinkage porosity, pores, cracks, and sand sticking in steel castings, more complicated technological measures must be taken than cast iron. SS 304 investment casting is the most common stainless steel casting grade, mainly due to its excellent corrosion resistance. It contains 16% to 24% chromium and up to 35% nickel, as well as small amounts of carbon and manganese. It is susceptible to corrosion from chloride solutions or saline environments such as the coast. Chloride ions can create localized areas of corrosion, called "pitting",聽which can diffuse beneath the protective chromium layer and damage internal structures.聽 About us HXN specializes in pouring ss 304 investment casting for a variety of applications. 304 ss is widely known and recognized as the standard for cleanliness and corrosion resistance in the food industry, etc. Grade 304 stainless steel is softer and easier to straighten than 316. Composed of chromium-nickel content, it may also be referred to as "18-8" stainless steel because it contains approximately 18% chromium and 8% nickel. Its properties include the ability to work in the "as-cast" condition and an austenitic stainless steel, which means it is non-magnetic, highly corrosion resistant, and cannot be hardened by heat treatment.
