Interesting facts about steel and metal
Why are nickel alloys so important for the chemical industry?
Nickel alloys play a critical role in the chemical industry and for good reasons!
EXCELLENT CORROSION RESISTANCE:
These alloys withstand a wide range of aggressive chemicals, including acids, alkalis and salt solutions. No wonder they are used in demanding environments where other metals would capitulate.
HIGH TEMPERATURE RESISTANCE:
In processes that require high temperatures, nickel alloys shine with their mechanical strength and corrosion resistance. Perfect for the petrochemical industry and high-temperature reactors.
When it comes to high pressure, nickel alloys are on hand! Ideal for use in pressure vessels and piping systems in chemical processing.
Some nickel alloys are chemically inert and do not react with most chemicals, making them perfect for demanding food and pharmaceutical applications.
LOW TEMPERATURE PROPERTIES:
Even in freezing conditions, some nickel alloys exhibit toughness and strength. A great option for refrigeration and cryogenics.
RESISTANT TO EROSION AND ABRASION:
Where erosion and abrasion are a challenge, nickel alloys make a clear statement and hold up.
EXPERIENCE AND AVAILABILITY:
Proven and well researched in the chemical industry, there is a wide range of nickel alloys available to meet individual requirements.
Overall, nickel alloys are irreplaceable for the chemical industry, especially when it comes to the most aggressive media, extreme temperatures and the highest safety standards!
What tolerances are important in surface finishing?
When it comes to using sheet metal, surface finish is a critical factor that often determines the performance and aesthetics of the final product. Here are some basic surface tolerances to be aware of:
- N6: 0,2 μm (8 μin)
- N5: 0,4 μm (16 μin)
- N4: 0,8 μm (32 μin)
- N3: 1,6 μm (63 μin)
- N2: 3,2 μm (125 μin)
- N1: 6,3 μm (250 μin)
FLATNESS ACCORDING TO DIN EN 10163-2 (EUROPEAN STANDARD):
- Class A: 0,3 mm on 1 m
- Class B: 0,5 mm on 1 m
- Class C: 0,7 mm on 1 m
FLATNESS ACCORDING TO ASTM A568 (AMERICAN STANDARD):
- Commercial Quality (CQ): 0,33 mm on1 m
- Drawing Quality (DQ): 0,25 mm per 1 m
- Structural Quality (SQ): 0,50 mm on 1 m
These tolerances play an important role in choosing the right surface finish for your sheet metal project. Roughness affects the adhesion of coatings and paints, while flatness determines the flatness of the surface.
Whether sheet metal is needed for decorative purposes or industrial applications, choosing the right surface finish can make a big difference!
