Chromium, nickel, molybdenum, vanadium, tungsten, cobalt, boron, copper.

This process removes/reduces oxygen and other gases during the steel processing

Degassification

This process removes/reduces only oxygen during the steel processing

Deoxification

What type of stainless steel is the cheapest?

Ferritic

Name the three types of stainless steel

Ferritic, martensitic, and austenitic stainless steel

Iron

What alloys make up steel?

Iron and carbon

This type of carbon steel have less than 0.20% carbon

Low Carbon steel

Low carbon steel have what properties?

Low strength, low hardness, high ductile, high toughness

Name the 3 types of carbon steel

Low, medium, high carbon steel

Name the 7 types of alloy steels

Low-alloy steel, HSLA, microalloy steel AHSS, Marginal steels stainless steels, tool steel

This type of carbon steel have between than 0.20% to 0.05% carbon

Medium carbon steel

Medium carbon steel have what properties?

Medium strength, hardness, ductile, and toughness

Steel is manufactured by what process?

Metal ladle metallurgy

This type of steel is between carbon steels and alloy grade with respect to cost and performance

Microalloyed steel

This type of metal preserves weld-ability, machine-ability and form-ability

Microalloyed steels

This type of metal provides energy savings

Microalloyed steels

High alloy steels contains how many % alloy addition

More than 8%

This type of metal processes shape bare steel followed by a finish and eliminates finishing operations

Pre-coated Steel sheets

Dipped, plated, vinyls, paints, primers, and polymer coating can be used on these types of metals

Pre-coated steel sheets

Metal ladle metallurgy can do what?

Provide final purification, alloy additions, dissolve gases, grain size refined
