Product Description
ASTM A387 Cr-mo alloy steel pressure vessel plates
Carbon steel changes depending upon the amount of carbon present. Low-carbon steel is softer and less brittle than higher-carbon varieties.
Low- carbon steel is the most common and cost-effective form and is malleable and ductile but has a relatively low tensile strength while medium carbon steel balances ductility and strength with good wear resistance. High-carbon steel is brittle, but possesses a very high strength, extreme hardness, resistance to wear, and moderate ductility, making it better able to be deformed without actually breaking.
Con-Tech’s carbon steel floor plate is a corrosion, abrasion and skid-resistant resistant thick sheet of steel with raised lugs in various patterns. It is frequently used as a flooring or walking surface in industrial settings as it is long lasting, slip resistant and can withstand the wear of forklifts and heavy pallets.
Steel floor plate is frequently diamond shape, called “diamond plate” which increase traction in locations where slip hazards are a potential risk. Diamond plate is chosen for both traction and cosmetic appeal. Our steel floor plate requires minimal maintenance which makes it a relatively inexpensive application for innumerable locations.
Con-Tech’s steel floor plating is extremely versatile. Our steel floor plate is used as industrial flooring and in a wide variety of other applications. Con-Tech steel floor plating can be found in shipping docks, staircases, steps, ladders, ramps, elevators, walkways, corridors, trailers and trucks, trench covers, garage and storage rooms and emergency and fire trucks, to name a few industrial uses. On the cosmetic side, steel floor plate can be used in innumerable uses like displays, signs, counters, and toolboxes.
We can deliver carbon steel plate, floor plate and coil plate through several ports, to almost anywhere in North and Central America. Con-Tech’s experienced personnel help find solutions to your carbon steel plate, floor plate and coil plate problems and work with you to find the right steel for your applicat

HEAT TREATMENT :
- Except for Grade 91, all ASTM A387 plates shall be thermally treated either by annealing, normalizing and tempering, or, when permitted by the purchaser, accelerated cooling from the austenitizing temperature by air blasting or liquid quenching, followed by tempering. The minimum tempering temperatures for grades (2, 12 & 11), grades(22, 22L, 21, 21L & 9), grades 5 are respectively 1150°F[620°C], 1250°F[675°C], 1300°[705°C].
- Grade 91 plates shall be thermally treated, either by normalizing and tempering or by accelerated cooling from the austenitizing temperature by air blasting or liquid quenching, followed by tempering. Grade 91 plates shall be austenitized at 1900 to 1975°F [1040 to 1080°C] and shall be tempered at 1350 to 1470°F [730 to 800°C].
INSPECTION AND TEST:
The inspection and tests that shall be alternately performed on ASTM A387 alloy steel plates include: tension test, Charpy V-Notch impact test, drop weight test, high-temperature tension test, ultrasonic examination, magnetic particles examination.
