OPTIM 700MC High Strength steel Plate. (OPTIM 700MC is the new name for RAEX 700)
Scope
OPTIM 700MC offers both strength and formability at the same time. The
surface quality, dimensional and geometrical accuracy and uniformity of
properties of this steel are all top class. Steel structures can be made
lighter, which means that the payload of machines and equipment can be
increased and fuel consumption reduced. The letter ‘M’ indicates the thermo
mechanical rolling of these steel grades, which is their delivery condition.
The letter ‘C’ means that the steel is suitable for cold
forming in compliance with EN 10149-1.
Application
Frame structures of mobile vehicles, surface structures of
commercial vehicles, frames and booms of forestry vehicles, crane arms and
other lifting equipment, load handling equipment and masts.

either singly or in combination.

Supply Condition:
Hardened.
Abrasion Resistance & Hardness:
The microstructure of abrasion resistant steel is
martensitic, which guarantees high hardness and tensile strength. High hardness
and tensile strength give a steel high resistance to abrasion.

OPTIM 700MC High Strength steel Plate.
The yield strength and tensile strength are tested in
longitudinal direction, but guaranteed both in longitudinal and transverse
direction. Elongation is tested longitudinally. Impact strength is determined
using the Charpy V test. For thickness less than 10mm the width of the test
piece is equal to the strip thickness and correspondingly the guaranteed values
are lower in direct proportion such that for 5mm a value of 2/3 of the value in
the table is guaranteed. Impact tests are not carried out on thickness of less
than 5mm, but the impact strength is guaranteed. ¹) Elongation A80 is used for
thickness below 3mm.
Processing
Heat Treatment
Welded structures do not normally require any Heat Treatment after fabrication. If stress relieving is required, however, it must be carried out in accordance with the following recommendations:

|
Stress relieving |
550 – 600 |
2 minutes/mm thickness, min. 30 minutes. |
Too high temperature and long treatment time may weaken
mechanical properties.
The strength of the thermo mechanical treated steel may
be reduced if the temperature exceeds 650°C, and for this reason normalizing or
hot working are prohibited.
Welding
OPTIM 700MC High Strength Steel Plate.
The welding is, in spite of its high strength, easier than the
welding of conventional softer grades. As a result of thermo mechanical
treatment, carbon equivalent values are low in relation to its strength. In
addition, weldability has been improved by selection of suitable alloying
elements and by ladle treatment. In design and workshop practice this good
weldability means that preheating is not necessary under normal conditions.
Before Welding it must be ensured that the surfaces of the
weld run are both dry and clean.
The Welding materials and methods must be
of sufficiently low hydrogen. Materials must be stored and dried, if necessary,
in accordance with the manufacturers instructions. The weld material
properties, strength etc. must, in the main, be the same as those of the base
material (matching).
There are, however, some exceptions to this general rule in
the case of high strength steels. This is the case for the higher
strength OPTIM
700MC steels, which mean that
consumables of a lower strength than the steel (undermatching) may be used,
provided that the weld is situated in a less stressed part of the structure. A
narrow zone pf material softer than the base material may be formed in the
welded joints.
The softer zone is similar to that in quenched and tempered
steel plate and does not usually affect the strength of the structure. The
width of this zone can be limited by avoiding the use of unnecessarily
high Welding energy.
Forming
OPTIM 700MC can easily be bent in the workshop. As a result of this,
components previously made by Welding can now be made by
bending, which shortens the throughput time and so reduces costs.
Successful utilisation of the excellent formability requires
the use of good workshop techniques. This requirement becomes more important
the higher the strength of the steel is. Worn tools, insufficient lubrication,
scratches on the surface of the steel as well as edge burns will all reduce the
quality of the forming. Also shot blasting of the surface may reduce
formability. Plates taken from cold storage must be allowed to warm up to room
temperature before being formed.

No limitations on bending direction.
Cutting
OPTIM 700MC can be cut easily using thermal methods such as flame,
plasma and laser cutting. When cutting mechanically, attention must be paid to
the stiffness of the equipment, the blade condition and clearance, and the
supporting of the work piece. Plates taken from cold storage must be allowed to
warm up to room temperature before being cut.

Machining performance
Download OPTIM 700MC the mechanical properties of the report, the report provides detailed performance analysis and application.
Principal Design Features
One of the most widely used precipitation hardening grades in the business. While soft and ductile in the solution annealed condition, it is capable of high properties with a single precipitation or aging treatment. Characterized by good corrosion resistance, high harness, toughness and strength.
Machinability
Long, gummy chips characterize this alloys machinability. It can be machined in the annealed condition, however condition H1150M will yield best results. Post machining solution treatment of parts will be required prior to final hardening if machining in this condition.
Heat Treatment
CONDITION A--Soak at 1900 F (1038 C) for 30 minutes and cool below 60 F (16 C) for complete martensite transformation. CONDITION H 950- Treat Condition A material at 900 F(482 C) for 1 hour, air cool.. CONDITION H925, H1025, H1075, H1100, H1150- Soak solution treated material for 4 hours at specified temperature, air cool, CONDITION H1150M- Soak solution treated material at 1400 F (760 C) for 2 hours, air cool, then re-heat to 1150 F (620 C) for 4 hours and air cool.
Welding
Successfully welded by common fusion and resistance methods, this alloy should not be joined by oxyacetylene welding. AWS E/ER630 filler metal is recommended if required.
Forging
Soak for 1 hour at 2150 F (1177 C) prior to forging. Do not work below 1850 F (1010 C). Post-work solution treatment is required prior to final hardening.
