The copositions of stainless steel AISI304 and AISI316 differ somewhat.The main component of SS304 is chromium,molybdenum is absen. Although SS316 is base on SS304,it has a comparatively greater nickel content and molybdenum. SS316 is better suited for usede in seawater beacuse it contains molybdenum,which makes it resistent to corrosion from seawater and high temperatures.Even though SS304 resists corrosion well,it will rust if it works in harsh environments for a long time. The chemical composition of stainless steel 304/3016 :   Generally speaking, SS304 is widely used in daily life such as furniture and public facility. SS316 stainless steel is widely used in marine hardware.If you have sufficient budget and high requirements for the product, you can choose SS316. If your budget is not high and you want to choose a cheaper product, you can choose SS304.Carrying out high standad quality control from raw materials to final finished product’s inspection is what an excellent manufacturer should have.

Hinge is common hardware in the market, hinge is a wide range product family that differs from material ,production technology ,application etc. This article is mainly about the stainless hinges with two different manufacturing process – casting and stamping . From the processing technology, stamping hinges are made by stamping and bending metal sheets to get the hinge components for assembling as the finihsed hinge;casting hinges are made by pouring molten metal into a mold and then cooling it to get the hinges shape parts to assemble into one hinge . From the performance characteristics, stamped stainless hinges are thinner, lighter, have a smooth surface, and good toughness, but their load-bearing capacity is limited that more fragile and more susceptible to breakage due to impact.Casting stainless hinges are thicker, stronger, and have higher load-bearing capacity, stainless steel casting hinges are much strong and steady for any application occasions . From the perspective of applicable scenarios, stamping hinges are mostly used in daily life, such as for doors, windows, furniture, etc. Casting hinges are suitable for heavy doors, industrial equipment and other scenes with high load-bearing and wear-resistant requirements. Due to the continuous advancement of investment casting technology, marine hinges are now basically casted hinges because they are highly corrosion-resistant and can be used for a long time even in the harsh environments .Marine grade hinges are also popular and required in the industries due to the advantages of the stainless steel casting process. Hiever has hinges manufactured using two different processes,both of which are of high quality.We will recommend the stainless hinges you need based on your requirements and application situations .We mainly produce casting hinges,as they have become important marine hardwares due to the continuous improvements in the marine application Can you guess which is the casting stainless hinge from the two photos below ?    

Because of its many advantages,stainless steel casting is a very effective process that is utillized in many different sectors.In comparison to conventional maching techniques,this casting production process is well known for its capacity to create parts and components with intricate shapes while providing a greater degree of design freedom.Because of its versatility,stainless steel casting can be used to create complicated designs,incluing parts with delicate detalis like threads and undercuts that are necessary for accurate fitting in a variety of applications.   Stainless steel castings offer excellent corrosion resistance which is also one of the feature of the stainless casting parts,this is particularly important in industries exposed to corrosion environments, such as marine, medical, automotive, and food processing. The used material is directly impacts the corrosion- resistance of stainless steel castings, with higher-grade materials have higher corrosion resistance.   Stainless steel casting methods includes die- casting, sand-casting, and investment casting. Each method offers unique advantages,for example, investment casting is popular for producing parts with high dimensional accuracy and smooth surface. HIEVER brand precision marine-grade hardware have the advantages of this casting method, achieving high dimensional accuracy and a meticulously surface.

Although stainless steel is known for no rusting, it is not permanently rust. To provide the best corrosion protection, all of our stainless steel hardware is pickled and passivated under the production procedure request before delivery to market. The fact is that not any supplier can 100% promise that their stainless steel(SS304/SS316) products never rust . There are several main reasons why stainless steel still get rusty ?   Low chromium content:Stainless steel with low chromium content has a fragile passivation film and i easily damaged in harsh environment. Corrosive media:Long term exposure to acids, alkalis and salts enviroments can damage the passivation film of stainless steel,leading to rusting of the stainless steel. Humid environment:In damp and poorly ventilated areas,the surface of stainless steel will absorbmoisture and polluatants,leading to electrochemiacl corrosion. Surface damage:The surface of stainless steel is scratched and worn,and the exposed metal is prone to react with external substances,causing stainless steel to rust. Surface-attached contaminants: Oil stains,dust,and other pollutants adhering to the shurface of stainless steel will be cleaned up in a timely manner,which will cause localized rusting of the stainless steel. In short, stainless steel is not really rust. Daily attention should be paid to maintenance for avoiding scratches on the surface of stainless steel,regular clean and protecting is required also, which can reduce rusting of stainless steel maximumly,also can keep the shining glorry surface. Hiever uses high grade qualified stainless material to ensure the strong corrosion resistance of hardware and parts from the source!
