321 is similar to 304, but uses titanium as a stabiliser. They differ in that they are resistant to intergranular corrosion after heating to temperatures in the carbide precipitation range. Applications include aircraft exhaust manifolds, furnace parts, heat exchangers, furnace parts etc.
302HQ is a specialised wire grade finding very wide usage for manufacture of stainless steel fasteners. 3% copper in the composition reduces the cold work hardening rate compared to Grade 304. 302HQ is the standard material for self-tapping screws, light machine screws as well as some bolts, etc.
The 316 family is a group of austenitic stainless steels with superior corrosion resistance to 304 stainless steels. They also have excellent toughness and can be used in the food, marine, chemical and architectural fields. Other applications include fasteners and screens for the mining industry.
This article discusses the properties and applications of stainless steel grade 304 (UNS S30400).
Scientists at Queen Mary University of London have created a new patterning technology that could recreate complex chemical environments. These complex environments can resemble the human body, leading to exciting possibilities for the biomaterials community.

Many industries have a problem of mixing up lubricants in a given application. A recent study surveyed lubricant users and found that using different types and viscosity grades that deviate from the standard manufacturer lubricant is the largest cause of equipment failure and increased manufacturing costs.
