A Quick Guide to Stainless Steel Types

Stainless steels are divided into four categories, depending on their microstructure at room temperature. Depending on what type of project you are working on, you’ll need a particular type of stainless steel to meet your needs. Here’s a short, quick guide to different types of stainless steel.

Precipitation Hardening and Martensitic Stainless Steel

This category includes steels two different types of stainless steel that have been modified to improve their strength, such as stainless custom 630. Though these metals have high strength and wear resistance, they are not as weldable or formable as austenitic stainless steel. Both stainless steel types in this group are magnetic and offer only limited corrosion resistance.

 

Austenitic Stainless Steel

Austenitic stainless steel has good to excellent resistance to corrosion, so it will not rust easily. It is also non-magnetic and is easy to weld and form into necessary shapes, which makes this steel the best choice for such a purpose. These steels are strong and contain more nickel than other types of stainless and they do not harden with increased temperatures. Aside from that, these metals also take longer to deteriorate under stress and pressure.

Austenitic stainless steels are divided into five subcategories:

  • Cr-Ni grades
  • Cr-Mn grades
  • Cr-Ni-Mo
  • High-performance austenitic
  • High-temperature austenitic grades

Ferritic Stainless Steel

Ferritic stainless-steel grades are alloyed with chromium, but they contain very little, if any, nickel. Because nickel is an expensive alloying element, this keeps the price fairly reasonable. Along with having good weldability, these stainless steels are also tough, magnetic, and offer good corrosion resistance. Carbon is added to some ferritic stainless steels in order to improve resistance to higher temperatures.

Duplex Stainless Steel

Duplex stainless steels combine many of the advantages of ferritic and austenitic stainless steel together. Their microstructure allows them to have high strength and toughness as well as a high resistance under stress. A magnetic and lightweight metal, these stainless steels are easy to form and weld. They have a high chromium content, though a low nickel content helps make them reasonably priced.

You need to know about any family history of eye disease. Many eye conditions are genetic. Discuss this with the older members of your family to get a better picture of the conditions.

Omega-3 fatty acids are great for your eye health. Ingest a lot of foods that are packed with this nutrient. Some of these foods are halibut, tuna, salmon, and dark green veggies. You want to have at minimum a serving of one of these foods each day.

Your eyes need to be checked out on a regularly basis by a doctor. If your sight is worsening, get checked out as soon as you can. This is why you need to get checkups frequently. Many of the conditions may be treated once they’re detected early.

Try wearing sunglasses. Your eyes can stay protected if you wear the right sunglasses. You’re going to need to stay away from this to not get macular degeneration or the problem with cataracts. For maximum protection, pick sunglasses that completely block UVB and UVA rays. You also have the choice of wraparound glasses that protect all sides.

Sunglasses are a necessity if you want your eyes to stay healthy. They will help your eyes by blocking UV rays. Buy sunglasses that protect against UVA and UVB rays 100%. If you drive a lot, get polarized lenses. They can minimize glare. Even with contacts that have UV protection, sunglasses are still necessary.

Pay attention to what type of heating and air conditioning is used in your home. These temperature control systems are a major source of dry eyes. If the heater is bothering you, try keeping a humidifier on so that the air stays moist. This is what can help your eyes to not get dry and irritated.

You are not the only one who is concerned about the proper care of vision. The minute that you experiences changes in your eyesight is the time to consult an eye doctor The tips listed here should help you maintain healthier eyes. Start using them now for the best benefits.…
