EN_US-Engineering-Product-Direct-Rolled-All grades Overview

Overview

Overview

Direct-rolled steel provides a viable alternative to cold-rolled and hot-rolled steel.
Tata Steel’s Ymagine® direct-rolled product line includes forming, structural and high-strength grades.

Consistent product characteristics deliver trouble-free processing and help you to maximize yield.
Ymagine® is pickled and oiled and comes in a wide choice of grades, dimensions and coil weights. All coils are weld-free. It means you can choose a product to match your requirement and optimize your processing operations.
 

Processing

Processing is straightforward with Ymagine®. Due to the low content of residual elements, it provides good weldability and can be welded using all conventional methods.
Ymagine® is coatable and has been tested for wet paint as well as powder coatings.

 A low silicon content means many users have successfully applied Ymagine® for laser cutting processing. For batch galvanising, Ymagine® can be ordered with a maximum silicon content. It can be continuously hot-dip galvanized without any restrictions and is suitable for enameling – although we always advise a trial first.

The main benefits of Ymagine® direct-rolled steel include:

  • end products of consistent and reliable quality
  • lighter and stronger products
  • faster and easier processing
  • increased output per tonne of steel
  • reduced waste and rework
     

Applications

  • Automotive components
  • Automotive seating and safety systems
  • Building and construction components
  • Drums
  • Racking
  • Lighting columns
  • Furniture
  • Grades

The product range includes:

  • a basic light gauge drawing grade: Ymagine® CS
  • four high-strength low-alloy steels: Ymagine® 45 XF, Ymagine® 50 XF, Ymagine® 60 XF and Ymagine® 70 XF
  • a structural steel: Ymagine® S36.

We are continuously improving gauge control, coil weight flexibility and lead times to achieve and maintain the best levels available in the industry.

0.098 < t ≤ 0.118 0.006 2
1. In some instances, the material will be supplied with a total tolerance of 0.009 inch, only on the coil head and tail and to a maximum of 66 ft. from the start of the coil.
2. In some instances, the material will be supplied with a total tolerance of 0.010 inch, only on the coil head and tail and to a maximum of 66 ft. from the start of the coil.
 

Tolerances on width

Width tolerances comply with standard ASTM A568: 2011
Width tolerances over, no tolerance under.
Closer tolerances are possible – please contact us.
 

Dimensions and coil weights

The weight of weldless coils can be specified freely between 560 and 1148 PIW.
Ymagine is supplied with trimmed edges as standard. Mill edges are available on request.

Description Dimension or weight
Outside diameter minimum 41.4 inch
  maximum 78.74 inch (Ymagine®)
  maximum 87.67 inch (mill scale)
Coil weight maximum 69,500 lbs 1
PIW minimum 560 PIW
maximum 1148 PIW
1. For Ymagine 70 XF the maximum coil weight is 55,000 lbs for thicknesses > 0.098 inch.

Tata Steel assumes a minimum and a maximum coil weight agreed upon with the customer on the basis of our normal production practices and an order quantity corresponding to this coil weight.
Usually a minimum coil weight up to 90% of the maximum coil weight can be requested.
 

Surface aspects

The surface quality of Ymagine is comparable to that of hot-rolled steel.
The roughness is comparable to hot-rolled pickled and oiled material i.e. 35 - 100 μinch CLA.
Ymagine is suitable for cold-rolled applications that are not surface-critical.
