Carlicia — this is an excellent article! And, I would offer the suggestion of taking the discussion to the next step — that of appropriate finishes for Stainless Steel. Maybe my experiences are unique, but I think not, since I have seen and heard many others complaining about post manufacturing corrosion….
Your insights from your experience with working on stainless steel are very valuable. Hi, Its really a valuable piece of information. Keep writing…. I find myself in unfamilar territory. Currently I am developing a new company division marketing and selling reusable stainless steel water bottles. I plan on manufacturing in China. My manufacturing partners are very helpful by providing their engineering team expertise to me as needed.
I am not in a position, at this point, to afford my own engineering consulting or in-house staff. My dilema is the use of ss v. In addition, I am concerned and trying to eliminate any leaching of metallic particles or taste into the bottle. The number one complaint of bottle water customers choosing glass over stainless steel is the metallic taste, or their foregone conclusion that it will exist.
Can you provide a reply wether or not ss is superior to ss for this product usage? Will ss provide any benefit in eliminating metallic leaching? Thanks for your comment! While I am no expert at water bottles, I can say that is the pricer of the two stainless steel grades.
This is because it contains more molybdenum which gives the material higher corrosion resistance. It also resists chlorides. I hope this helps! Carlicia — thanks a lot for this article! That is a good question! We do not have that information as the majority of our applications are not necessarily used in explosion zones.
I would recommend a bit of research. Thank you! I am in a quandary regarding and where the finish is critical. I understand machines better than , however electropolishes better. Does machinability trump electropolish-ability or vice versa? Cost is not a factor — only quality of finish. Great question! This is definitely a quandary. It will depend on the application that the part will be used for.

Difference Between -SS Stainless steel vs SS Stainless steel While using steel, many people are confused between SS and SS , which steel grade to use in the working environment so that the material used in the application should last for a long time.

We've added this more basic breakdown that includes just about every other grade of stainless steel we've heard of:. Why choose stainless steel over other materials? Some of the many benefits of stainless steel can be found below: Corrosion resistance Lower alloyed grades resist corrosion in atmospheric and pure water environments, while high-alloyed grades can resist corrosion in most acids, alkaline solutions, and chlorine bearing environments, properties which are utilized in process plants.
Strength-to-weight advantage The work-hardening property of austenitic grades, that results in a significant strengthening of the material from cold-working alone, and the high strength duplex grades, allow reduced material thickness over conventional grades and therefore, cost savings.
Long-term value When the total life cycle costs are considered, stainless steel is often the least expensive material option. Impact resistance The austenitic microstructure of the series provides high toughness, from elevated temperatures to far below freezing, making these steels particularly suited to cryogenic applications.
Fire and heat resistance Special high Chromium and Nickel-alloyed grades resist scaling and retain strength at high temperatures. Stainless steel is such a material. The longevity of stainless is the result of the alloying composition and, therefore, it has a natural corrosion resistance. Nothing is applied to the surface that could add additional material to the environment. It does not need additional systems to protect the base metal, the metal itself will last.
Stainless steel needs less maintenance and its hygienic qualities means that we do not have to use harsh cleaners to get a clean surface. There is little or nothing to dump into the drain that could have an environmental impact. Stainless steel products complete their service life. Hygiene The easy cleaning ability of stainless steel makes it the first choice for strict hygiene conditions, such as hospitals, kitchens, abattoirs and other food processing plants.
Aesthetic appearance The bright, easily maintained surface of stainless steel provides a modern and attractive appearance. Ease of fabrication Modern steel-making techniques mean that stainless can be cut, welded, formed, machined and fabricated as readily as traditional steels. The above is courtesy of Suncor Stainless. Type Analysis of Stainless Type Carbon 0.
Silicon 1. Manganese 2. Chromium It is non-magnetic in its raw form but can become magnetic as the microstructure is changed via cold-working. It is the most common type of austenitic stainless steel. It is often used for products in mild corrosive environments, in automotive applications, in the construction industry, and in the dyeing industry.
